Meh, not really all that impressed to be honest. even if it is just one picture at the moment.
All your really doing is just re-skinning a model that someone else made. And even that is slightly diluted by the fact that alto of it isn't actually drawn by you, and is more of an assembly of pieces.
Maybe you should take up actual 3D modeling or drawing actual race cars. Even really crap results from those would impress me more than simply putting together a texture.
On that same note, Could you try and upload some thing more high quality or at least a bit larger in the future?
