great subject! :) I would have preferred to see more of the car in the shot, as well, the lighting (which must be its display lighting or that in combination with your flash) is making the shot look a bit flat, but I'm afraid I don't have any practical suggestions on how to improve that.
As a pure asthetic preference: would it have been possible to get a sideview of the car instead?
very nice image, i think there is something more you can do with the backround, other than that great work, i see a nice focus and good lighting. umm i am going to give you a 7 because i think you did a good job, but i think you can do more.
Nice subject. I like the colorin this photo. Your composition is good but it seems to have a snapshot quality. Perhaps shooting it from above would have made a good shot. (I don't know how much control you had).
