There is so much potential with this shot. I think that you should focus more one the black and white characteristics of the photograph. Neautralize the backgroup and make it completely black ( this will allow the white of the car stand out more) right now the sub-particles of debris in the back ground, like the small word elf, distracts from the main focus of the picture). Some of the car should dissapear into the all black back-ground to give it a sense of mystery. right now the white-ness of the car is duller that it should be. The most important thing with car shots is the shine, second only to the angle ( Note: next time you might want to angle the car in the shot, that way you can suggest movement and a 3-D aspect to it).
