My nephew would like this. The sound track is along his style too. Fit well.
What you did looked great to me.
Just in the first minute or so (0:39-1:03) it seemed like the camera was staying in the same spot.
I think maybe if you juggled that around in post it might shake it up a bit.
One shot I was hoping to see was where you sit on a ramp, the guy comes up, does a flip as he's passing over your head, and your basically doing a vertical 180 with the camera. Ahh, jeeeez, I didn't see it man.
Yeah, make some more.
//edit: The shot I mentioned above is pretty much what you have at 1:40-1:44, except I imagined the camera more in the apex of the curve, or something like that, the center of the arc. But yeah, that's almost what I was looking for. Just go up about 2 or 3 feet on the ramp next time and if the guy doesn't crash into your camera and destroy it, it should be a cool shot. Maybe house it in a box or something.
