hey mate,
there's some good ones in there. I especially like the 2nd one (lowndes with a bit of flame)
and the last 2 of courtney.
I know you didn't intentionally capture the fist in the foreground as courtney crossed the line, but i think it kinda works with the whole shot.
Also the shot of Ingall sticking into the tires is a great capture.
On the Lowndes shot, notice that you've left him some room to go in the frame... ie, the car is positioned on the right of the photo, and would exit the shot to the left. You have left some room on the left hand side of the shot, and this makes the picture work. (that, and the nicely captured flame)
in the couple pics below (GT and brightey), there is more room behind the cars than in front. Really, you want that to be the other way around.
Just something to work on as you go. If you have cropped these pics any, then it's just something to take notice of next time you do so.
All in all a great effort though. I know how hard it is to navigate the street circuit fences!
Nice work. Hope you enjoyed your weekend (rain and all)
