So this is mostly personal preference, but this?
I hate this.
Put your panels closer together. Stop wasting my time and cramping my finger with an entire screen of nothing.
Okay so, character art is decent. It's not blowing my mind or anything, but you're obviously going for a very simplified, cartoony style, and it feels very storybook-y, which works given the nature of the the comic. The same can't be said of your environments.
those do not look like a storybook-y simplification of trees, they look like children's drawings. There's definitely a lack of environments overall, lots of just flat gradient colors which makes the characters feel like they're floating in a void. Do not draw backgrounds. Backgrounds are for suckers. Draw environments.
You need to think of the place your characters inhabit as another character in the story, and give it the same, if not more, attention. Tell me something about where
your characters are, is it shiny and clean? Old and dilapidated? Rustic and homey? New? Used? Cared for? Neglected? Cluttered? Clean? Tell your reader these things through the places you're drawing.
Use reference. Always, always, ALWAYS use reference. Don't just assume you know how to draw a tree, look up photos. Google is your friend. Draw some for practice, pay attention to different types, the shapes they make, the way leaves grow and bunch and hang. What do they look like in the specific season you're trying to portray?
I've recently come to the realization myself that it's not enough to just not be afraid
of using references, you have to be eager
to use them.
this right here? This works. Give me more of this.
Not the characters, those... need a lot of work here, I'll get to that in a moment. The church looks good though, it feels very solid and real, you obviously used reference to see how actual church windows are constructed, the belltower and side wings look accurate, it's great. The only thing I'd say is missing here is some texture; are these smooth and polished stone walls, or did you just not bother drawing an indication of the brick texture? Can't tell. Should there be ivy growing up the sides of it, or is it well-cared-for? If so, we should see some manicured grass around the edges of it. At the moment it's just sorta... floating there. Give me those little details, and this will be by far the best looking thing in your comic. Hell, it already is based on what I've seen, but it can go further.
I think she's supposed to be yelling angrily here?
I honestly can not tell what sort of emotion I'm looking at.
Remember how earlier I said your character drawing is fine for the cartoony simplified style you're going for? Yeah, forget about that for a minute, your portrayal of character acting is atrocious.
Honestly, the lady looks like she's broken her neck and suffered severe brain damage while trying to do the macarena.
Reading a little forward, it seems like you've gotten somewhat better about this:
this is good. This feels like cartoony character acting and I want more of it.
That said, just because your style is cartoony, don't think that means you can get away with shoddy anatomy. This poor boy has dislocated his shoulder here, his pose hardly looks natural at all.
With all of my aggressive criticisms, I can see very clear improvement from start to finish. Your lines feel cleaner and your characters feel more solid. I feel like you're already on track to fix a bunch of the stuff I'm talking about here, it just needs to be a conscious effort to improve (especially including environments in the same panel as your characters more often)
