Can I be perfectly honest and a teeny bit picky?? I love the sky and the contrast to the "orange-ness" of the car, but personally I don't like the lens distortion. Makes the car's front end too bulbous.
This is the really picky bit. The angle on the back wheel, probably due to the uneven ground, and the dirt on the front tyre. I appreciate you were probably rushed for time etc but I think a car shoot should be "pristine". The car is clean, and if the dirt was washed off the front tyre it would just add to that clarity giving the tyre that "new" feel.
This is just my personal opinion, don't take it as criticism as such as I've not produced anything like what you have in your portfolio.
