Well actully, a rough version of that stunt was tone by Plethzorb a bit before it, the only difference was the lack of the packer. Either way, it is just a stunt, there are obvious differences between yours and TB's stunt. He hit the wall sooner and stopped on the grind.
Watching the rest right now.
Edit: Okay, it was pretty good. I say 6/10. Music wasn't so great and the stunts were eh, but I liked the editing.
