Aquaplaning

A very nice concept - the angle of view is pleasing as is the crop and the reflection off the track surface. It gives a good impression of the car moving into the frame of the photo.

However, what brings this image down is the focusing and camera shake. The focus point is on and just below the number on the door - ideally, it should be on the windscreen. To avoid the camera shake, you may need to work on your panning technique (smoothness is everything) but using a faster shutter speed (say 1/180s) will help. Depth of field could also be better as you'd want to see more of the car sharp / in focus, but a switch to a higher ISO film should help you there.
