Very nice. I'd say the one thing that kinda bugs me is the ground, esp. where the tiles get bigger and fuzzier towards the camera. The ground should be in focus at least where the car lies, and maybe closer to the camera, depending on the camera's depth of field effect you're trying to simulate. So, let's pretend you shot this. From some basic photography knowledge:
If you used an aperature of f11 or higher, everything would be pretty much in focus, from in front of the camera to the building.
For an f-stop of 8 or lower, and you focused on the car, then the background and foreground would be slightly out of focus from the 8, and more so with lower f-stops (wider lens opening).
Also, is the ground supposed to be the same color as the background plate, or is that more of a beige sidewalk?
A: The car is stunning, esp. the reflections and the lighting.
B: Fine tune the ground and dof, and it should look like a real photograph.
