Congrats first on your new 20D you need to update your camera profile in the profile.
As for the picture.
Challenge: N/A
Technical: 10 Sharp, Good DOF especially with shot like this with very fast movement.
Composition: 8 A more dramatic shot would have gotten a 10
Appeal: 8 Its a nice picture but I wouldnt put it in a frame.
Overall: 8 If this was a challenge this is how I would score it.
Yeah, I ride as much as I can. I raced this past weekend, then as soon as I was done I grabbed my camera and started shooting. I race mostly at Budds but have gone all around.
Cool thats where I thought it was. My local track is Highvoltage MX park(home of Broc Hepler)and of course Steel City and HighPoint. Broc rides at Highvoltage alot during preseason and during breaks. I will email you some photos if you like.
