Love the shadow. I'll bet you do too! ;^) Very good job of stopping the motion here, especially the skateboard. You may take a minor hit on the slight blur of the boarder. The burning of the edges is discrete enough and effective in bringing the viewers eye to center. The color tone seems a little green to me, but I'm not the best with colors. You should do pretty well with this. Good luck in the challenge.
excellent capture and great example of this sort of shot. your choice of angle is grand, really enhancing the airborne nature of the picture. having the board upside down only enhances this. the blue tinged duotone works well in a moody and urban way, which suits it too. nice and sharp, has not been excessively burned round the edges. top stuff - 10
