Bill,
This is so impressive. I wish I had that car to shoot! So this was really shot outside. Any added lights?
A minor suggestion, to maintain the powerful Magritte vehicle coming out of the frame, add a shadow of the left hand frame on the edge of the back of the car. The bodywork of the car is so bright that it is at no point seen to be behind the frame on the left edge. Similarly, extend the well executed diagonal shadow from outside the frame on the lower left, to curve over the adjacent left lower picture frame which then will be correctly placed.
While you are at it, I might also want to burn in a little the chrome grill as that is special.
