#1 is good.
with #2(and having never done skating much and never skate photography I'm not the best judge) I'd want to lose those houses and the strip in the background, + he's a bit overexposed at the edge.
#3... I realise you skaters love using the fisheye in every single angle even when it doesn't apply, so just tone it back a bit, his heads completely distorted and the fisheye is only bringing out that brick. Also shutter is too long, either make it faster or use a brighter flash, you don't want him to be invisible as he is.
