nice work! I like the 1st and 4th photos best. On the first, the reflections are a little distracting and the crop is a little tight for my tastes. The rear of the car needs a little more lighting too I think.
I like the crop on the 4th pic, and I like the lighting/coloring on the background. Probably the only thing I would add is a little more light on the face of the rear wheel to match the front.
3rd pic is great - as stated in another thread, just close the garage door
