@NekoSensei So I'm tagging you since I don't replies notify people. I'll do a detailed discussion, then do overall closing thoughts.
Overall, I would rate it as generally good art.
This is a harder question to answer or position to take for a few reasons, but mainly because you're a one person team and I don't know what your educational background is when it comes to art. I would say it has a modern webtoon aesthetic, but lacks well rounded foundation of art fundamentals to be believably professional.
Panel By Panel Breakdown.
When I saw this first panel, I liked it. But it isn't drawn by you, which isn't bad or a problem. This panel sticks out to me since it doesn't blend well, for me, with the character art. And another thing about this panel is that the perspective and the level of detail doesn't match the backgrounds of other panels.
I think the bottom panel should have come after the top panel so to make the reveal more dramatic.
I do like this panel as a reveal, but it's not very dramatic. Honestly, the first time I looked at it I didn't register that she had horns and a tattoo on her chest.
This panel is fine and so are the two following panels. I'll do a draw over later. I really like the colors here.
This is where I'm going to bring up the backgrounds again and say that they lack detail. I'm not saying fill these brief panels with a lot of detail. Rather, I'm saying just add a bit more to make things look grounded. It's this really difficult balancing act, because this next panel has more detail but the characters still look out of place.
There are few things with this panel (that will be detailed later) from the shading, to the perspective, to the speech bubble and font choices that are off to me. Though, that may come down to compression due to uploading.
I'm going to talk bout this panel as well. I skipped a couple but what I want to call out here is the hand/arm of the guy, and the main female lead's eyes. Eyes are a big part of my critique. The eyes are pretty, but pretty eyes will only take you so far. So I'm going to skip this next panel and focus on the next panel.
We're going to talk about this panel.
Draw-Overs
Sorry about the quality, I had to screenshot these.
Proportionally, she's very inconsistent. He head size is fine, but her arms are too short and her legs are extremely long and one of them is wider than the other. The are arms are also two different lengths, and it's not obvious that the one planted on the wall is supposed in perspective:
1. Her entire arm is completely stretched out.
2. She is standing so close to the wall that, if her arm was straightened out, it would be in front of her and therefore closer to the viewer and the hand would appear bigger.
Though I didn't go that route with this draw over
So here, I have her arm up, because the closer you get close to a wall, to compensate for the loss of breathing room, your arm would need to shift up or down. The arm is also slightly foreshortened because it's in perspective. I also made her legs significantly shorter to better match the proportions of the rest of her body.
I think the word of the day for you today is: perspective. Characters have a hard time believably existing in the places you create because the perspective is off enough to be distracting, at least to me. And perspective begets proportions. How the perspective works for a panel will inform how your characters' form and proportions are going to be interpreted. And the perspective and proportions do not make sense in many of these panels.
It's hard to tell the angle at which we're supposed to be viewing this scene because the perspective is flat, based on the lack of foreshortening. It would be far more dramatic and interesting, compositionally, if this panel was from an ant's eye view, i.e. a bottom up perspective, like from the scared guy's perspective in the scene. Or if she was bent over, which would be more intimidating.
I think this redraw here is more dramatic and intimidating, and puts more focus on her horns and the tattoo, which really don't stand out in the original panel. And you can add more detail like making the flames more prominent
Another thing I personally find amiss with this panel is the lighting. Supposedly it's night time (and raining but no one looks wet) and the two characters are in a back alley. But rather than a dim light coming from the moon or a street lamp that's around a corner and half a block away, these two characters are so brightly lit, it's like she's attacking him in front of a storefront. And not just any storefront, the storefront of a lamp shop, it's so bright. Instead of looking at her horns, I'm looking at her right thigh because it's the most brightly lit thing in the whole panel. So turn down the lights, bathe the scene in dark blues and purples. Looking into lighting references, you can go on pinterest, especially if this comic is going to mostly take place during nighttime.
With this character, there are just things that, again, don't work proportionally.
1. Like I indicated, the knee and the foot of right leg are pointing different directions (look, I don't mind some broken anatomy, but it's harder to get away with it if your characters are more realistically proportioned)
2. The torso is at an awkward length, being a bit too short and the pelvis isn't really accounted for here.
Also, I noticed his left arm is placed very strangely. Okay, peep this. This character is supposed to be leaned back, right? So, how is his left arm are casting a shadow on his leg? The leg that's out in front of him. if he's using his arms to support his weight, and he's leaned back, they would be behind him and therefore, wouldn't cast a shadow on his legs or torso. For his arm to cast a shadow on his leg, he would have to be leaned forward. And who would be leaned forward if you're scared? Anyway, here's the draw over.
I closed off the posture more, because I assume this character is afraid, and also because I'm going to assume most people are not flexible enough to lean back, with their legs wide open and their arm stretched out in front of them. I like the chair at my desk too, but sometime you need to get up and try out a pose to make sure it makes sense.
I will say, in the middle of all of this, I really like the way you do hair. It's so pretty.
Okay, so for this panel, the characters look like they were pasted into the scene, and not drawn with the scene in mind.
1. The character are brightly lit again, even though they're in a nightclub.
2. The wood grain texture looks out of place
3. The shadows are inconsistent (on the glasses on the table and also on the characters whose light sources are coming from two different directions).
I want to get into the head shape of the guy in this scene, but only briefly. It's so round, that it's off putting. No one's head is that round. And the way it tapers at the based of the head makes it seem like his neck is too thin to support the head's weight. I struggle with this too, to be honest, but consider making your necks a little thicker.
Let's hop back onto lighting. I have to assume the light source is above them based on how the shadows are place. But not completely above them, since their faces don't really have shadows. But then, the shadows the glass cups make are very stark. That would mean the light shining on them is very bright and coming from one direction. But then, the pitcher that's on the table is casting its shadow in a different direction from the other cups and from the characters. Moral of the story, figure out your light source before you lay down any shadows so you don't confuse yourself and make your art look extremely amateurish.
Okay so, for this panel I want more focus on the text. I would recommend changing the shape of the speech bubble to a more oval shape, just so the letters aren't so crowded. Also I would move the "BAM!!!" to be closer to the hand and not so separated from 'the action.'
Let's get to the next panel. Okay, two things
1. The hand on the shoulder.
2. The eyes
The hand is too far forward and missing the palm. If he's that close to her, either only the fingers would be on the other side of her shoulder or his thumb would be visible and his fingers would be behind her.
I'll admit, B doesn't make much sense, but it's only because they are suddenly turned away from one another. The last thing I'll touch on here is the girl's eyes. I can accept that they are different in this panel due to an expression change, but the detail in the eyes does not match the detail presented in the rest of the comic. Like I said, yes, the eyes are pretty, but they're also pretty out of place. I would say the art and polish needs to live up to the standard that the eyes are setting, or you should stop making it obvious what you spend the most time on and make the eyes less detailed. Comic are, unfortunately, more than drawing characters and drawing them well.
Last one, finally. Something tells me you mainly draw women and feminine men. And there's nothing wrong with that, but it then does make drawing more masculine or harsher features on characters very difficult.
With the red draw over, I followed your lines and I noticed the the eye closest to the camera is significantly bigger than the other eye by not in a way that is proportional. The face lack structure; the are planes to the face that inform the placement and proportion of the features. The eyes are on the front of the face and are the same size. Here, they're not even looking the same direction. The nose would protrude a little further from the face and it's kind of unclear where the chin ends. Now my redraw isn't perfect, but the placement and size of the features are more coherent and proportional with each other.
We finally made it into the clearing. I'll wrap up here and detail into a couple more things. Overall, this is good, though I wouldn't say professional. I can tell you more of at a beginner/intermediate stage in your art journey. You're taking on more subjects than just characters from the shoulders up or fully drawn, posing without a background. You are good at what you do, but you're in the phase of trying to do more than what's in your comfort zone. There's a learning curve in comic making and the things I would say you should focus on for now is anatomy, perspective/proportions, lighting, and composition. Pinterest is a great resource and there are plenty of artists on youtube that have videos going over all of those things. I say apply the things I've said here to future chapters and don't go back and redraw this. Nothing about this prologue is severely off putting and I think you'll gain a sizeable audience. But anyway, good luck and I hope this helps!
Nitpicks
I don't know why, but I don't really like the font for the speech bubbles. I think you should change it, but you don't have to if you like it.
