Okay, I would like to give some constuctive critisism here, if I may. :)
1st shot - great spot, I think maybe that as the car is black, selective colouring didn't help much, as it doesn't make the DBS stand out. Good shot anyways. ;)
2nd shot - colours are very nice on that one, I like how the blur turned out, aswell as the crop.
3rd shot - now here selctive colouring has done it's job, made the car stand out, I like the effect that the surroundings make, looks like the car is alone there, although I do see something white on far right, maybe another's car side mirror? ;)
4th shot - trully amazing panning shot, sharpness/vibrance really make details on the car stand out, maybe the only thing I see wrong is that you could have left a bit more space on the bottom and crop a bit more from the top. :)
Thanks for reading that, David.
