Not bad...
To make your movies smaller, there's one huge recomendation I strain for everyone, who is new or who does not know the full understanding of sound.
In flash:
Click sound and insert whatever sound you wish to be in your movie.
Under the effect selection is a "Sync" selection. Click it and change event to start.
This stops the problems of movies from playing if you stop or rewind the movie. I don't know if you did that, but it is an important reccomendation to people who use flash.
