Bike racer concept

My latest work created with sketchbook pro and with my genius graphic tablet.This looks much better then my previous entry.I played with perspective,and I'm not sure is it right.Also I didn't mind to much about technical details.My aim was to render it the best I could with learned skills so far.I think if i will keep with practicing it will be even better,next time.I hope you like it.

update:I made some changes with gradients and layer filters in gimp.Now it looks much better.
