I like the flare in this - I even like the background figure, which I found distracting in a couple of similar shots. It works here due to placement, size, and angle I think. About the only thing I'd change would be to have the hand in the picture. Very good shot!
I really liked this shot. The flare and shadows worked really well. Good lines and color. I am glad that the guy in the background wasnt further out or else you may have cropped him out. He adds a nice touch to the shot. I also like that the board is not flying but just the guy with his feet off the board. Good capture.
Best on show in my opinion.
If you are getting comments about the flare from the sun being not good, ignore them. This turns this good shot into an outstanding image.
Best of luck. I would love to see this win.
