In terms of the shots, the rolling shots are good, but ones of the whole car would be better. I think the sun shining at the camera is incredibly amateur and takes away from what you are trying to capture as the car goes really dark. Other simple things like on 3 or 4 of the pictures, you've got almost the whole car in, yet the spoiler is out of the shot, or front bumper, to me it looks like you've jolted the camera at the last minute and knocked the car out of frame.

All this is IMO of course and should be taken with a pinch of salt. I don't proclaim to be a pro photographer but I have a fair idea on taking a decent shot of cars as that's all I really take photos of!
