Skateboarding pics, want improvement.

well they are good color and timing, i suggest using the rule of third and dont use fisheye angles without a fisheye... other then that.. just dont try getting ass shot and ur good

At first the composition struck me as boring, but I'm digging the shadow in shot #1. Seems like the focus is a little off in that shot, though.

I like the second one because I've never seen an angled sign post used as a rail before.

Cool shots, just work on your focus. You may also want to add something else (sorry this is where you have to get creative), to add a bit of interest to the shots.

The first one was shot at 10mm and there were a bunch of people standing around so i croped out as many as i could. The third Pole jam pic seems as if his left hand came out a little stretched from being at the angle on the lens. but i the moment of capture. I know a flash would really clear some of this up as i could set a faster shutter speed. The onboard flash limits it to 250. is there a way to over ride that, just to flash during the day to lighten the skater from the background? thanks

as someone who took an 'ass shot' these are pretty cool. I like #2
