I've read through what you have up so far, and it's looking like a good set-up. Some thoughts:
- Artie didn't originally seem to be behaving that oddly to me? He just struck me as an excited camper until he insisted on diverging during the nature walk.
- There are a few panels - commonly the first in an episode starting at #7 - where the text is extremely small. I'm on desktop and still had to zoom in, even though there was plenty of blank space so it could've been a normal size. Just keep that in mind and be sure you keep the text at a fairly consistent size.
- A lot of comics I read will have funny little comments in the descriptions, which I quite enjoy. Obviously that's not actually a part of the comic, but it lets the author's personality show through, I think, and helps endear you as an author to your readers, which could be helpful regarding ink and such. Currently, you have pretty cut-and-dry summaries of the episodes. I would suggest making them more like you commenting on the episode, judging the characters' actions, etc.
- Spell check. I found Minnesota spelled "Minisota," then immediately followed by the correct spelling.
That said, the actual story line is definitely interesting and I think the pacing is good. Some more character development would be good, like MTDG said. I agree that Karen is my favorite so far, though Artie seems like he could be fun as well. I'm a writer, not an artist, but the art is solid and pretty clear about what's happening. Curious to see where you take it!
(Sidenote: I just realized I read the whole thing without liking any of the episodes; I'm gonna go back and do that now. I did actually read them at a normal pace and am not just spam-liking
It bugs me when that happens so just wanted to clarify)
I'd love some feedback on my novel if you're game! It's the story of two strangers who run away from their lives together, with plenty of drama and secrets along the way.
