I know the skater is the focus but there is alot going on around him that I feels is wasted space. I think I would have cropped the photo left of the skater and right next to the guy across the ramp, eliminating him from the picture. Next, I would crop down from the top eliminating some of the top of the pipe that you see at your feet. Just leaving the people in the corner and the skater sliding towards them with whatever top of the pipe is left after the crop. Also think sports photography we know hes skating so you could adjust your DOF or blur the background of the lower park. There is just alot compiting for attention.
