I've come to this through the 350D page - and I can't believe it isn't up near the top of that page. There are certainly elements I'd want to correct with another session - impact would be gained from a crop that placed the skater a touch more strongly, and keeping an entire shadow would have emphasised the disconnection from the ground - but your sense of the graphic in the background, the brightness and toning across those surfaces really speak of the bright sun - those should surely have got you a higher score ... neat work
VERY awesome!!!!! Your background and composition are amazing. I feel a gasp in my throat thinking about that poor fellow a split second later after this shot was taken. Ouch!
This is not my top pick for excitement but is among the best in presentation. I'm drawn to the clean feel of the shot. Hard to put my finger on it but I really like it. Good luck!
