Shooting cars is no easy task. I like clean lines around the body if possible. The spoiler is hard to see against its background. I dont like the pier coming out the windshield. As for the driver's side, there should be some form there. Move the car so the paint reflects some unidentifiable white. As PhotoXopher said, we dont see the original so its tough to know how much Photomatix altered your pic. Glad you didnt go over the top with the sliders. Its a nice shot and Im just knitpicking.
