This is merely a practice exercise, I have no attachment to the work. The car was parked (obviously since there is no driver) 
I sharpened the car, added motion blur to the BG, added the tire smoke, radial blur on the front tire, desaturated everything, and darkened all windows. (Not in that order.) The result is below. I want it to look better. Opinions, please.

And here are the final touches: Desaturated more and added grain. Again, open to any and all suggestions.
