Really cool!!
The shadow seems off to me too. I feel that there is just a lil too much black spill all evenly around the car. It makes it hard to recognize the ride height of the car. It makes it look overweight and squatted down too low.
You can clearly see the height at the front right of the car but struggle to define the lines of the car towards the rear. Maybe a little less shadow in this area would help.
