Couple pointers.
I'm not in the mood to give a fully fleshed out review, so here's some things you could have done to make it a bit better.
Actionscript is your friend. It just wants to be loved, but everyone is afraid of it. All you need to do it speak its language and you will never regret your friendship. Try making a start and replay button. It will help with the video auto starting. I don't know about you, but I hate it when a video starts on its own without me telling it to. Same with replaying. Both of these buttons are super easy to make and will make your video much more clean and professional looking.
CREDIT YOUR MUSIC. Unless you wrote and played the music yourself, you should always credit/provide a link to the artist who worked so hard to make your music. I can't tell you how much I hate it when people don't do this.
Final tip. When you're making a replay button, select the final frame of your video, go to the actionscript for that page, and type in the stop command. It will stop the video on the final frame with the replay button. It's a but of a rookie mistake, so I just wanted to make sure you didn't miss it.
That's all I had. Nice video with some excellent visuals and audio syncing. I approve and hand you my woots, sir. 4/5 8/10.
