nice images. Composed well.
my picks from your set are 1, 2, and 8
1
I like this one due to the building outline fallowing the car all teh way to the edge of teh frame, its a unique angle that shows of the stance of teh car as well as shows off the business end with the slicks.
2
Is a very good front shots, because it give sthe subject a bit of personality, kind of an in your face, "what are you looking at" stance
8
I like because of its vantage point, you werent afraid to get on teh ground and use the DOF to your advantage, the technique is good here as you were able to get the front of teh car in focus and maintain the DOF to the rear.
good shots.
