Mike,

I agree with modz365.

Could you have taken 1, maybe 2 lights from that side to light the other side of the car? That would light the interior, and the ground on that side more. (may sound silly. But it makes sense) It just seems obvious that the only light source is coming from that side.

5 lights on one car is a bit much. 3 is more than enough. Especially @ a little less than full power.

Again, tricky shot to pull off.
