Nice shot and car. I like the overall composition of the shot but I think I would like it better if you were able to get the reflections of the trees off of the windshield. Maybe moving yourself or the car into a different position you could have achieved this. Although it may be possible to clone out. I like the lighting on the front bumper and hood of the car as well. Also I think having a bit more light fall on right side of the car would have been better because it kind of blends into the background. I would also consider shooting without the lights on. Its a bit too much white in a shades of grey and black photo. I think if you had done it in high key the lights wouldn't be distracting. although I prefer the low key style you have chosen for this image.
