Sure thing! I'll definitely help with more sprites! ^_^
Name some targets for me and i'll get busy!
I do abstract stuff fastest, like The Little Humphis, normal people, well, it depends XD
I'll take any request but real weird monsters for now. I have trouble with detail and shading on stuff like that lol. I don't think any of your characters fit THAT extreme category so you're fine ^_^
I'll go ahead and fix The Little Humphis' color, but the blending of the joints and stuff may take awhile to get it right, I have a game project myself that I work on almost all the time and i'm easily distracted by it lol XD
Ok! I'm off to finish the recoloring, and i'll post the next sprite sheet up soon as I finish with him!
EDIT:
Too much? Too little? Too bright?
Sorry for takin' so much time to get him right XD
