the only thing that id have to say would be to let the shots go on for a little longer. i understand the affect you were going for and it was good but maybe let them go for a bit longer ... that flat off the a frame at the start looked sick
i liked the idea of cutting it to only see a portion of the trick for the teaser, but some of the cuts seemed a bit random. it might just be me, but try to time it more with the music your using next time.
