I agree 100%.
Also, I do not think you did a "very good job" synching the music with the video, like others said - but that is okay for a first time movie I think.
The editing/clipping isn't outstanding either, but like before, this is very okay for a first time video.
It might not be everything but it do play a big role in the video.
For the camera angles on the other hand you could have done a much better job. It was a little "un-professional", if you can say it that way.
A last word on the tweaking; you did not perform any stunts that where very "special", "unique", "outstanding", ect. with the tweaked PJC or Caddy so I think you should turn it off and try normally.
You might say it's just as hard to land/perform tricks, but then why don't you just do it normally?
For the opening trick, that isn't special at all. I did a similar trick in my upcoming video (waiting for FilePlanet validation).
Hope I wasn't too hard on you, I had no intentions about making you bite the dust, whatsoever.
