Very, very snoozational
Your lip-synch was adequate... which I guess is good, considering it was the one thing that moved -at all- in the first 3/4 of your flash, the last quarter being taken up by a simple, pointless left-to-right landscape cycle. Here's a hint: it's called a Flash -animation-. You might consider actually having things move during the movie. I mean, come on -- you had the rays of light coming through the trees. How hard would it have been to have them move a bit and alpha in and out? You could have made a much better flash with a minimal amount of effort. And here's another hint: try spending more than a day on one of these.
Get it together, man. You can do better than this.
