I like to see you work out how to center the car more in the picture. I've always felt that cars that are in the middle of the image make more aesthetically pleasing pics..
This would involve doing a bit of clever C+P work to generate some more ground, but I think you'd be capable of doing this. It's a nice bg, but it's also a shame that it's rather desaturated. Perhaps you can use that to your advantage and use that to draw more contrast on the car, like the effect some photographers edit on their photos.
