Not too bad.
I can see you did it out of your spare time. It could realy be interesting if you had the guy turn back and do the next trick himself. Even add a little more story, like one guy can't do a trick the other rubs it in and the n BAM the pro dude crashes his $h1t. Either way it was a neat effort. i really like the bord flipping and spinning. Those made it look believable.
