You've captured a pretty good angle on this Audi. The star reflections from the sun are in a good spot to attract the viewer's eye although I wish the big sun reflection could be toned down or eliminated. I would also like to see some more detail in the tire. Without fill flash or a reflector, it is very difficult to capture the full range of tonality when the sun is high in the sky. You've done a pretty good job with that although you need a little more detail to the right of the photograph. Your composition is basically good. I do see some internal lens spots in the sky toward the left so you should try to shade the lens more when you are in this situation. You've got a nice blue sky and that enhances your image. The shadow from whatever is next to the car is slightly distracting since it is of a "boxy" nature while the car has curves. I agree with the comment someone made that it would help to include the entire wheel.
if the right portion of this car were a bit more exposed (less dark anyway) I think this would be one wicked awesome shot, (still great though) I love the curves and colours, and the shiny newness of this car.
I like the angle you've chosen to shoot this subject at and I also like the negative space. Both serve to accenuate the curves nicely! However, the lighting is uneven - the front of the car feels a bit dark and the flares are too distracting to my eye. Good shot - 7
