Sprite size is fine. But why using so many colours if the distribution of them are nothing nearly CvS shading?
- Hair looks like Sindel in CPS2.
- Gold arms looks like a giant latex glove painted in yellow. Same for the kneepads.
- Needs muscle definition.
Any way, I strongly suggest you to look at Kiwi's tutorial. And if you need any suggestion/advice/etc feel free to say it here. Someone may be helping you
I swear there was something cool here!!
