These look pretty funny, but I do have some small points:
- You are using a lot of unnecessary colours that you almost can't see
- arms(but might be preference) looked a little fat to me
- don't think it always applies to pixelart, but it is mostly not advised to use pure black or whites
Anyway, here is my own edit to clarify these points. Also, I just wanted to play with them
. Just did the side though, but I hope this helps you a bit
In this edit I also changed the body shape a bit, since it looked quite odd to me. But again, that's probably just preference
. Might do the front pose later if you need some more help after this. I'm also interested in seeing a mock-up of your project though, since then you can see more easily what's wrong or doesn't fit(I think, not very experienced with pixel art
).
Good luck!
Edit: Owh, just noticed he hasn't been online since november :')
