Too much slow-mo, skatings fast! Show it! I like seeing closer to real time footage of skating, maybe a little slowed down for something nutty. Even if you were filming handheld, i think it would give it a cool look. Also, the slowed down footage looked choppy, were you shooting 24fps or 60?
Not to be a downer about song choice, but this might be one of the more played out songs (Minus awolnation's "sail").
Confidence is the feeling you have before you fully understand the situation.
