I like working with systems and I read too much Brandon Sanderson so this is how I have to approach a magic system or I just can't work with it usually for my own writing
I've never heard of kachou fuugetsu before! I had to google it. Is this on a novel currently posted or one that's still being worked on?
And yes! I was like 'if these people can just control the way light bounces off things then why can't I have werewolves??'
It's because I'm an anime nerd and it's a Japanese thing, but I think it's a really cool underrated four element system. There still are the four elements, because everything loops back to it and it's mostly symbolic, but fire is birds, because phoenixes so fire is also the element of healing magic and nurturing magic in conjunction with the flowers which is growing and constructing magic. And moons and water is to do with divination and reflections and changing how things are seen. It's in the works for the mini-series jam actually, but I've been kicking it around and world building for ages.
Tbh I think because I wanted to and I like it should be an acceptable reason for including anything.
My magic is an extension of the user's will and wishes. Not something that can be learned at Hogwarts. Its effect is powered by how emotional the user is and how bad the user wants results.
The same charge/mana on the same spell will have different outcasts depending on the user's will in the present. And the magic itself has a will of its own.
You need to be in balance of your own person. The surroundings and the settings and the magic. Everything has to be I balance for you to control it's outcome.
And that is not easy
Whenever I write magic, I draw off the concept of auras/energy/etc., where the magic comes from your aura and the focusing of your energy. Magical crystals are also pretty common.
In my most developed magic system, there are eight different elements. Someone with a particular affinity for an element is referred to as an "Elemental," with that person being able to use spells of their own element more easily, having weaknesses to other elements, stuff like that.
Incidentally, the most powerful magic in this storyverse is the combination of all of the elements in equal parts, which only certain legendary beings have been able to do.
When I draw magic I go all out depending on the kind of magic, intense glow and lighting for energetic magic like fire and lightning. Or lots of movement for magic that involves physical objects.
The more I go out with making magic look epic, the better
I have different magic systems in my series, as each race has its own unique magic power.
The one currently relevant in my series is a sealing magic which take forms of glowing blue "runes" on a surface the magic was sealed in (usually papers) when activated and if the magic is sealed on consumable form of liquid it becomes a magical potion.
In my story Genii's magic comes from an ancient stone that shatters and embeds into his palm. It's set in a (medieval) world without magic, so it'll be interesting to see how all the other characters react - he's been banished from his village thus far. So not a great reception. 
(Initially) I'm portraying the magic as pure energy. It's difficult to control and contain - especially as he's young, quick tempered and stubborn. The energy (in the stone) gradually builds up until it reaches maximum capacity/charge. If the energy isn't expelled (or used) somehow then the stone will eventually start to overload and become unstable (rendering Gen mentally & physically unstable too). It glows, crackles, burns and is "loud" as Genii says - which is really a subconscious warning to do something about it. 
He doesn't know any of that yet though, so he's "holding it in". 
smaaaart
Eventually he's going to start to figure it out and use it. 
And there are a lot of amazing things he can do with it too, but he has a LOT to learn (mostly self confidence) and soooo many obstacles in his way. It's going to be really, really, really tough (because I am a terrible person).
And this is just the first stone - the "Soul Stone". Sorry Gen!
Visually - it's blue and shiny! 
Short answer: Yes
Long answer: What looks cool at the time, separated in orders of strength. Vague gestures and things happen is the weakest, then runes are either prepared or they appear when there's more energy put into the spell, then the eyes start glowing and the gibberish runes appear in neat circles with nothing drawing them. If it glows, sparkles, crackles, creates wisps, or rises up like smoke and flame, I'll take it.
As for effects from other comics, I find Clockwork (hiveworks I think?), Stray Souls (WT) and Castoff (Spiderforest) have pretty nice ones!
It's a good approach. I always appreciate a just go all out epic approach.
This is a really cool concept. I love the whole magic shatters and ends up embedding in you thing. I've only read 1 thing that really dealt with it and that was a fanfic and it was the sunset that got embedded in his palm (it was that kind metaphorical magic world).
Gotta love the classic blue shiny.
This is awesome. I'm surprised there don't seem to be more systems that use graduations like that (maybe there are and I just haven't spotted them) when it seems to make a lot of sense.
As a reader, any magic concept is fine with me.
As an author... 
I had the hardest time firming up details for my magic system because I was already 30k or so words in to my story before I realized how crucial some of the information about the system was going to be 
I’ve tried to write magic in such a way that it’s understood that there’s specifics, but it’s also rather vague. So, there’s glowing and runes, and technically spells, but its never explicitly spelled out. There’s different categories of magic, slightly reminiscent of elements, but broken into different categories. I’m a fan of soft magic, if you couldn’t tell, and only wrote down most of this info to make part of the plot make sense otherwise it would all be “and there was some magic - and magic is magic, so no explanations needed!” LOL 
My story has a bunch of magic systems, depending on what circle you follow. Most of my characters are alchemists but I got some that get animal powers, I got others that bend physics to their will...I wanted to try and do a rock-paper-scissors with magic systems, so that although there are a lot of them, none of them are so powerful as to be able to take over the earth or something. They have a lot of weaknesses and in-fighting between circles cancel eachother out.
As for how I show it, I keep it fairly abstract in the book--where you can see the end result, but I don't have people chanting phrases (that was always corny to me), instead you hear sounds of them shuffling through their alchemy equipment, or you see the damage they do when they've achieved some animal strength.
As for the comic I made of the same story--it was entirely black and white, but when we discussed or showed magic I used the color red.
Inner-magic-within concept. Popularized by shounen mangas, which inspired by ancient/ new age knowledge such as Chi/Ki, 7 Chakras etc. I still like them the most, maybe because I was born around battle shounen mangas. 
My magic system is like a very simplified version of Naruto's + Hunter x Hunter's magic system, it only contains 3 elements. I'm not gonna make to so technical like the mangas did though.
I portray it sometimes kind of generically with seals and magic spells.
Though I love abstraction and surrealism so I don't shy away from really odd visuals you don't normally see in fantasy.
But in a very specific comic of mine that's more a psychological horror than a fantasy comic, there's vague hints magic is going on such as a castle my character Yuna lived in becoming cracked and old when it was once new and pristine. I made it subtle to make viewers question her sanity or if there was some sort of magic at play.
they both take place in the same universe and I wanted to test what it would be like in different settings.
Usually I draw it with blood or fog. Sorry I don't have any examples on hand.
Magic in my universe is something naturally possessed by certain beings, so they usually don't need chants or runes. Only a few characters use physical objects for magic. The rest do so naturally, like a bat flies or a dragon spits fire.
That was probably a poor way to explain it. I mean, you know how Pokémon don't usually chant from a magic spellbook before using their powers? That.
I'm still ironing out the kinks of my magic systems, so a lot of things are subject to change, but for the main magic system in my story: magic comes from the stars, generated as mana and channeled by the magician through a "medium", traditionally though magic staffs but usually wands, however anything can be used as a medium (a character uses a sword, another uses tarot cards, which take on the appearance of playing cards in their world). As a result, everyone kind of has a different way of doing it, but the result is usually a glow/aura around said medium called... well, an "Aura". The shapes and colors are dependent on the user and their personality, for example, one of my characters, Jupiter, his Aura color is red and takes the shape of something that looks like lightning, while his brother's is more of a calmer, regal, blue aura. I wish I had photos to describe this part better, but I still don't.
In the REALLY old days they used to use runes, but that's spoilery and I'm keeping it under tight wraps so I'm not talking about it, lol.
Other magic systems in the story work like:
one magic system that only works if you use something, for example, picking up a flower from the ground requires you to use a bit of mana to heal the flower, which means that the magic is really only effective for healing.
Another is centered on illusions. You can only change the appearance of yourself and not the surroundings around you, and mana is generated from the user themselves.
This is always really cool, you don't see enough stories with different magic systems (I suppose because one is hard enough for a lot of people).
Haha, is it weird I've totally never thought about Pokemon as magic before?
This is really cool, more personalized magic within a standard frame is awesome.
I draw heavily from Akashic Records of Bastard Magic Instructor in that respect, their world has Mana and natural magic and spells are described as basically a form of auto-suggestion - you're told spell A does B so when you say Spell A you expect B and the world responds. Which of course leads to the teacher pointing out these students who think they're so great don't actually understand magic, they're just parrots and he can do their little lightning spell with just "well paralyze or something" totally deconstructing their view of magic as something super occult and sacred. And my world does something similar with each magic user having slight variations on spells that do basically the same thing, but the variations in phrasing and patterns can lead tracking families and groups. For instance, early one they realise one of the characters has a specific teacher because only his students use the phrases Silver Queen in their water magic.
Magic in Space Pirate is fairly loose right now as far as abilities go. There are 4 elements and everyone is born with a natural tie to an element. But only certain people are actually able to actually use magic to manipulate the elements - which in this case, is really the energy and matter of the universe. These people are scouted out to become high ranked military officers. Some people over time gain the ability to tap into another element and are able to combine the two to form a new element. Your normie class of character has to tap into their life-force to use their magic. While some underwent training to "expand" their available life-force and to become more efficient with it, they still will eventually exhaust and even kill themselves. As opposed to space pirates, who in this universe, have a natural "reserve" pool that they can tap into before tapping into life-force. They can burn an absurd amount of fuel before they even begin to show signs of fatigue. It's inspired by a couple of magic systems. Naruto, Dragonball and Star Wars in particular.
This is always cool to have a limit on the amount you can do. So magic doesn't become overpowered and used for everything. I've got something similar with Mana and certain magic users can enhance their Mana reserves by working with another type of magic user and sometimes forcibly sharing reserves.
As a reader, I don't honestly have a preference for how the magic is used by a character. I care more about the overall story then I do about something like that.
As a writer, I try to mix it up but for the most part my magic is usually instinct based. A character is born with a certain ability and they can just use that ability, but they do need training to truly control it. I've had magic in my Celestial Children Trilogy where it becomes like a second metabolism to a character and will literally eat at their body if they don't balance using it vs not using it. They have a dominate magic, one they can use easily with little damage to their bodies, but then an opposite magic that could kill them if they used it too much. Most of it was elemental based so like Wind magic users could be killed by doing earth magic, that kind of thing.
In my book Draygon Frost I have both natural magic and totem magic. Natural magic is where the character is born with a certain ability. The MC has ice magic, there's shifters that are born with the magic to shift into specific animals, but then the various magics can in turn be infused into totems to allow non-magic users to use it. So there's a changeling potion that can change their appearance to anything, ice totems that can be used to refrigerate food or just generate ice, fire totems keep things warm or light things on fire. A seduction totem will seduce a character and so on (my totems are kinda an uh duh with their names LOL Naming has never been my strong suit). Then there's something called a crystillium flower that will actually poison a magic user and stop them from being able to use their magic and I have a bracelet that turns the magic user into a mindless being that obeys the command of the person who controls that bracelet.
If I ever get back to writing it I'll have another book where there will be amulets that allow for magic use. I haven't worked out all the details to that "science" since I haven't written the book yet, but the idea is going to be that there is a certain race or blood line that can use these amulets. To anyone who doesn't have that connection (whatever I decide on it being) the amulet is otherwise useless. That one is going to be fun to explore for me because it's going to be all dependent on the amulet and what it can do as to what magic a person can do.
