Sonic riders rouge

I do like the shading and lighting of the board and rider, I would like to comment on the legs, they seem too straight and have void of life to them, If you could put Rouge in a better stance with her knees bent into a more life like position maybe it would work and the wings are too big too. Not only that but the background seems to plain, for where Sonic Riders is set which seems more futuristic than anything rather. Here it just seems generic. Other than that, good job but still room for improvement in this picture.
