Good looking shot. The only thing I would suggest is to give a little more room to the front of the car. Give it somewhere to go.
Technically, it looks good. I'll agree with Don on the composition. The only thing I have to offer would be to clean or re-black the tires after driving it over the gravel, at least the sidewalls. That may be the look you're going for, but with the rest of the car being so clean, I feel like the dust on the tires is a little distracting.
You could clean the tires in PhotoShop
