The balance between the colors looks very good. I especially love the fact you didn't make any part of the body only one solid color and instead gave the skin a nice mixed look with both black and white without making the white too bright or too sudden with the patterns. It looks natural, in my opinion at least. The only thing that comes to mind as a very small negative is the amount of white on the head, maybe. It somehow looks a little too dense around the front of the face compared to the rest of the skin which looks to have a way more 'mixed' look with both colors, not giving either one a clear dominance.
Overall though I think it looks very good and is something I'd definitely want to see in the game. :)

The colors are perfect.
