You need to work on your camera technique as there is way too much zooming going on there. Have you watched many skate videos? Check a few out for inspiration on some angles to try out. The best seem to be tight pass bys and low shots.
Yeah, the filming was done by my friend, who i was a little less than happy with his filming, but i tried to do my best with what was filmed. The main challenge was the editing, as we only had one camera, and with all the shots we had to take (considering this type of skating is more following than tricks) it became a matter of continuity in the video, and I think I did pretty well with that, but yes, future videos will probably have a better filmer.
