Once more, lighting and tones rule on your shots.
The 1st one is my favorite, by far. What franz said is spot on, it looks like he's slowing down, waiting for some competition to catch up, but looking at the rearview mirror (the fact that's dead center on the shot enhances that) all he can see is a blur...
Man, this is poetry.
Also, amazing reflections on the car, specially on the left, over and on the headlight.
2nd shot I really like the blue tone, almost like a light hue. The tarmac looks great on the bottom of the image but the blur you applied in the upper part seems a bit off (most probably due to the lines on the tarmac not being straight to begin with, not your fault) and kinda ruins the speed effect.
3rd shot has a really cool GT4 blur and apart from the very subtle tones I really like it's composition and the angle in which you took that shot, very close to the camera.
You're above all an excellent photographer, Cod. 👍
