Hello! I just found your work through the "Critique requested" tab!
I really like your work, the expressions and color choices are really fun and exciting! I think you just could try placing your characters in space a bit differently, as with this illustration, I think it would work better if her hand wasn't cut off like that, as it restricts the piece a bit. I also think that when you place your characters, especially when they aren't facing the viewer, giving them something to look at might make for a more interesting piece. Still though, Eggnog is a really fun character and I like her vibe a lot!
