Nice
That was really cool. The part with the sk8r doing tricks off of the animators hands was very original. The music and jibber jabber worked well as a soundtrack. The only thing that seemed a little strange was the "motion trail" thing. It's a cool looking stylistic effect, but in certain parts, it kind of distracts the eye from focusing on your awesome animating abilities (mostly in the scenes with busy backgrounds). That's minor stuff. This was cool as hell, and I hope you make more.
