You've got some really great shots there, the cars in the air are my fav, the very first picture with the back of a car with all four wheels off the ground, fantastic. And there is another one with the car turning on sand, looks like a manufacturers shot of their new buggy.
When I've shot stuff I think less than a quarter I've taken are really good. I upload what I can so people can see their cars but takes too long editing them all and going through them, you've done better selecting fewer here. They're pin sharp too, what lens was it ?
Great stuff
