You know, you said it's not your best but posted it anyway. Don't get discouraged. The thing is, there is nothing going on here, unless you wanted it parked in the middle of the track. Make it interesting. Take multiple shots, pick the best. This track is great for photos. I would avoid having the horizon align with the roof of the car. the car seem a bit blurry. Adjust your aperture setting to make it brighter. In the way you setup your shot I expected movement, so play with the shutter speed. Move the camera around and look for interesting reflections. If not here, some other part of the track. Try this shot again, good luck.
