I'm going to be brutal here, forgive me
1. I'd like to see a larger image as the artifacts really detract on this one, I know you can't post it up, but the resizing has killed this one. I do like the angle, it is nice and sharp but the car doesn't jump at me (which I think comes back to the artifacts).
2. I think this style of shot requires uber sharpness to work better. You seem to have captured that from the 1 back.
3. Great Op shot! Would love to have a slightly wider angle but you don't get that luxury! Dial in some more contrast and saturation
4. Great flames, great placement, this is the winner of the photos here for me! I would like a little more foreground personally, but I still really like it as is!
5. Well done, but it doesn't work for me, I think it is the background cars that do it, I'm not sure. They seem to look wrong for where this car is in frame. A tighter crop cutting the roof of at the top of the R in FORD seems to make it a better photo for me. Also I think a little underexposed.
Other than that, well done, jealous as all hell!
Cheers
