Thanks for the comments, everyone.

I was pretty worried about too much going on in the first version, since 15 seconds was all I was allowed to work in and certain things need to be on long enough for people to read.
The faux 3D camera trucking effect on the lawn was pretty impressive.
That was the most difficult thing to work with, too. Flash can't handle effects like what I was doing with the grass, especially when I had to export the final thing for display in the pre-movie (pre-preview?) ads in a movie theater. Which not only is 1280x720 resolution, but 59.94 frames-per-second. Converting an image sequence to video was the only way to go.
