If you have videos to post, they really should go in the Net-Vid forum.
But on to your video...I thought it was excellent. You're right about the strong beginning; and yeah, at the end, it seemed like the video deflated a bit. I love what you did with the text at the beginning, lol, and I like the various effects you had. The timing was really good too.
If you have time, I say wait until there's better footage to use, then make another with an ending you can be happy about. ^_^
