Very Inspiring!
If that was a trailer, than it's an excellent job! What you did in that animation was quite awesome (hmmm.... maybe I should be making flash too). I've been to both of your websites, it was very interesting. Your music actually fits the mood of the animation, yes, some scenes were quite crappy (and the ending part looked like you've just traced the whole Spiderman thingy). This movie seemed like you've an interest in "free running". However, you would to clear all this confusion the next time you send in an animation! Good luck.
