Nice pictures, I like the colors and the sharpness.
The third one is superb, lots of people think about cars when they hear the word "motorsports" 8) :wink: hehe.
As a fan of motorsports I suggest you have pay a visit to the Nürburgring. I bet you will be impressed by the places where you can shoot photos from. If my 70-200mm f/2.8 VR lens arrives this week I will go the Nordschleife on Sunday. If you ever want to visit it and need a guide, please send me a message then.
