Silver the Hedgehog Gajinka

My first full digital art ever (all Corel Painter 9). Meant to be a practice/speed paint but I put it off so much that I never realized it has been months since I first started this. 0_O

This was meant to be the humanoid form of Silver the Hedgehog in Sonic Riders: Zero Gravity. Does it show?
