Highlights around the wheelarchextensions seem a bit too strong, try dulling them down in places with the eraser or a layer mask. The highlight on the gap on the door in on the wrong side of the gap in the front, it should be on the back side of the gap, not at the front of it. And at this point the car does look tooney, but I am sure you will sort that out once you start fitting it to the bg.
Cheers!
