Tem alguns defeitos como Megablaze disse

Yeah good shout, the leg was off there, *tweaked!*. It's meant to be viewed at 100% just so I'm not too concerned if it just shows on the zoom :). Color count matters to me for file size and when using work in games I program its nice to keep it low. I try to think hard when choosing colors but 'fan art' isn't a factor in the color count, for me anyway it comes down to functional (games work/filesize) and personal dislike of overdoing it - in the description I meant I have a few quite similar shades that cropped up by mistake that I'm not to bothered finding and fixing right now :).

Added smoke to koffing and fixed the ekans' bottom line to ground him ^^

C&C: Jessies left leg looks kind of awkward, it bends inward right before her foot, i think it should bend outward, and have her foot facing slightly inward. Her right hand is a little hard to see, and when i zoom in, it kind of looks like studded gauntlets because of the lighting, not really sure how to fix that without repositioning the arm.

Everything else i like, and i wouldn't worry about the ammount of colors when its fan art, pixelated or not, it looks better with the right colors then it would with limited colors.
