I quite like the light pool in the first shot - got some interesting shadow and drop-off there that works well with a white car. DoF is a bit shallow though, making the roof line and the interior out of focus. Not a major thing, just something to chew over.
The spray booth shot is okay but I can see there's a difference between the shadows under the front splitter that don't match up. Also, the wing mirrors look like they're set to different positions and the front left wheel is lit, whereas the driver's side front isn't. It's got potential but i think you deffo need a flash inside the car to give it some punch.
The last shot is interesting because of the high, wide viewpoint and the almost centrally composed subject matter. Probably the best lighting of the set and the workshop environment works well, as if the car has just been finished. Again, a small speedlight set behind the car could have given a bit of rim/back lighting and helped pick out some detail inside the car. Food for thought I suppose for future.
All in all, it's a nice trio of a pretty neat car. Loving the black roof BTW. Good man too for including a set-up shot
