Hey, I like that last one, you just need a bit more definition on where the car is in the picture, maybe use a pen to outline the cars details.
Forgive the crappy scan, but heres my idea of what the next BMW M3 2-door SHOULD (read: not will) look like.
Eh, the front end on mine came out all crooked-like, but I dont care.
BTW, when is there going to be a drawing comp around here? I need some inspiration!
