the picture has excellent framing mate! for picture b i would clean up the fog light a little bit, its kinda jagged if u look it it. also the hoodline is kinda smudged around. if u want to do something with the tarmac, try selecting only the tarmac, no grass, no dirt, no rumble strip, no car, no sky, just tarmac, and run a slight motion blur going towards the vanishing point. just my opinion ^^;;
edit: i just noticed the billboard behind the viper. u might want to clone stamp the tree to cover the billboard up. it kinda makes the car look bleh.
