Its good except for the text in back looks pretty bad and you could have made it darker and more slick looking.
I hate the text in the back, there is too much going on back there. Also I would have made the diameter of the spotlight a little bigger because it looks like the car is sticking out from it.
With an overhead lighting the shadow would be short and under the car... The lighting would have to come in at a shallow angle to get that long of a shadow.
