Thanks for the feedback Owen and gsosa! I was happy with the lighting on the fisheye shot, but where I had the flash on the long lens angle didn't seem like it was doing so much. It's just all trial and error at the moment for me with distance of the flash from the skater and then adjusting flash power. It's been fun, though, learning a new skill.
I shot a trick yesterday where the clouds and light were constantly changing and each shot was looking a bit different, but I'll post those later for some critique when I finish editing them.
