I like the idea here. Straight profile shots are hard to pull off though. Plus, the cantered horizon doesn't add anything for me. Perhaps if you went lower, and took the shot from about the drivers 10 o'clock, just to get a bit of the front end, it would have added a bit more life to the shot.
What appeals most to me here is the wonderful shadows created by the low sun. Tilting the image so the car is facing uphill I feel is correct to give the image a more comfortable feel even if that means the stone chock is on the wrong side. On my old laptop the rear quarter of the car appears blown. I had a look on my mobile (which I feel is better calibrated) it isn’t that obvious. I do like those shadows and I believe that is what you are really trying to portray here. Well done.
