The protagonist being a 40 something year old soccer mom with three kids, a husband, and mortgage who must save the world from some existential threat and make sure the kids get their juice boxes at half time
I want more monster x human romances where the human isn't a total pure/virgin beauty and the monster is more than just some human with red skin and horns (or a shifter with a completely human form, or a human top half and some other creature bottom half). Put the monster back into these things, man!
And have the relationship address issues different than normal things humans go through. I was a bit disappointed with the manga Monster and the Beast by Renji because the monster and the guy's relationship seems like it can just happen between two regular humans. And it was just like other romances where one party worries over their self-worth and jealousy triggered by their partner's blasé playboy ways. : /
All reasons why I started my own webnovel tackling these things.
Also I wouldn't mind seeing a happy or comedic take on apocalypses? And more characters working in positions other than office jobs or at freakin' cafés.
More sophisticated and diverse comics and the readers who appreciate them. I was going through the first 300 top comics on Webtoons and they're all very similar.
@IndigoShirtProd you mean humor comics that are actually funny.
More interesting character designs. Especially in the shounen or whatever webcomics call this genre. I don't want some white polo uniform and black haired copy paste mc if I'm gonna follow a huge ass story. The personality may stick with me. But it still kinda bothers me that... well. the design is boring.
Good endings I can learn from. There's few really satisfying endings out there (since many stories end up being discarded and unfinished, mainly, but even in the finished ones it's very hard to wrap up a story that leaves the reader with a good feeling), so I'd love to have more of them.
If you have any recommendations of finished webcomics with endings you felt happy with please send me a link, I'll take a look 
I really like stories who cares about a character having a family and also showing at least a bit of their dynamic. Most the time a persons personality is because of the way they grew up and the people around them during that time and I sometimes feel like comic's just forget someone came from somewhere and had a past that made them into the person they are now. Even more bonus points for me if a characters parents are fleshed out too and have their own pasts.
I think......more experimentation when it comes to storytelling, characters, premises and art style.
something that makes me think "it looks like i haven`t seen everything yet"
Of course, well implemented conventional stories work on me too, but every once in a while i love to see something unique.
I want to make some comics about suicide/suicidal thoughts but I find it really hard to cover the subject. I am afraid all reactions will be something like, you need to seek help or that I may give the wrong advice to people with serious problems.
Fair judgement instead of people only liking a webcomic because it is anime style or because it is LGBT. Don't get me wrong, there are BEAUTIFUL webcomics which have one or the other, or both, but it is because they were well written not simply because they have those things.
Romance with humanoid robots that aren't just perfectly human-like androids but with like. White hair. It can be either a robot and a human or only robots, I just wanna see robots bein cute!!
...I guess I just really miss mtmte 
Weird, but I'd actually like to see more laid back sex related comedy comics? Like Oglaf. (NSFW)1 I feel like there's a lot of untapped potential for awkward situations relating to people trying to get laid. Also funny, consensual sex stuff is just very cute to me for some reason.
This would be nice too. I have a comic dealing with topics like suicide, abuse, and such, but it's definitely in the very unpopular/niche category. It would be nice for more people tackle darker, more sensitive topics. When done right they have a lot of potential to make great deeper works, and tap into a larger array of human emotion and character... depending on what kind of story you want to make.
(Great, now I really want to read JtHM again.)
I know how you feel. I'm personally a paranoid about releasing my comic, but fuck it.
If you're not quite sure how to do it without harming/annoying people, I do have some advice:
There is a huge difference between someone who has suicidal thoughts and someone who wants to kill herself. That is not to say they are not both struggling, what I mean is that someone who thinks about suicide is not yet in a position where they feel like the have no other options. A person who is willing to kill herself, on the other hand, tends to be more logical about it. She has been pushed so hard she legitimately thinks there is no other, no better way to solve this issue.
You can write about either "stage", they both have serious struggles, but too often I see people who used to have suicidal thoughts and never went to the "I'm going to kill myself now/very soon" stage, and when they recover they think you have the same thought process in both stages. I'm really glad they never got close to dying, I really seriously am, but when they recover, I feel they can sometimes say really harmful things to people. Something that personally hurts me a lot is the idea that life gets better. I hear it all the time. It really doesn't for all people. When you are pushed so hard to the point where suicide feels like the most logical option, there is totally a chance that life won't get better. When you tell people that life gets better and that they have friends and family that loves them, or whatever other encouraging thing people try to say, it often makes it worse, because when you are pushed so far as to want to seriously die, you don't have a good family, life won't get better, and the last thing you need to hear is from some stranger who doesn't know you situation at all, that they know better than you how your life is. And if you do have a good family or friends who care, such comments can often make the person feel even more guilty and therefore more suicidal

Eh, that was literally just one piece of advice. And look at how long that got... I'm not going to write more now, eh, I hope this at least helped a little bit.
I finished my first two pages and I'm going to publish it later today. If you want read that for inspiration, go ahead.
I can't read JtHM because during all my moving, especially when I was forced into the hospital and in the process became homeless, I lost a lot of shit.
While these topics are really niche, I do think there is enough of an audience to make a living of off a comic like that. You do need to be really proactive though. Show your comic to goth youtubers, goth/punk bands, try to market it really hard on social media. Sitting on your comic will probably not get you views. You have to get them from the outside.
There's actually quite a lot of completed comics on Tapas it's just a matter of sifting through everything 
One that came to mind actually was Strays by Samantha Whitten
Great story with good characters and a pretty satisfying ending
Hope your able to find more 
I just read the first chapter and it looks really nice <333 thank you for the recommendation! (I also don't know many comics on tapas yet because I'm quite new ashfjklsaf I guess I'm more used to fan comics, which, at least in my experience from the ones I've read, are almost never finished c': but I'm glad to hear that's not as common here <3)
You can download a ZIP file for the series here2. I haven't read the comic in 15 years, so most of my physical copies are long gone.
Marketing depends on how you handle the subjects, though. JtHM would definitely be for the gothy, horror crowd. Although if you were to take a more serious, slice of life approach, your audience would be very different. My comic is more of the latter and it attracts people who like Psychology, fans of general darker stories, and those who have had similar experiences. Because of this I advertise wherever since there's no specific group my comic would appeal to.
There are also people who take a more autobio, black comedy approach, which attracts an entirely different audience. But I'm sure they would still attract readers from the two previous examples as well, given that comic still plays on dark subjects.
There's a lot of variety in how you can tackle dark topics. It would be nice to see JtHM style comics, though! There aren't enough horror comics out there as it is, so ones dealing with topics like suicide, and abuse are extra rare.
And it's no trouble, we're all new at some point
