I like the heat from number 2.....
As for being dull. Not really. However, this kind of imagery has been done to death and its the best you can get given the awful public photog access at Silverstone. Look for some fresh angles, shoot themes, focus on certain parts of the car etc.?!?!?!?
Gary, do a search for my BritCar stuff mate, you may enjoy it if you like motors and are newish here.
Nice one,
Diego.
