Points for learning fast, but here is a tip
You learned techniques in Flash fast. However, you should practice your drawings, because you can't do too much with imported images. Another tip is to compress your music. Take all of the music you are using and convert them to WAV. Then import those WAV files and use them in your movie. Then you go to publish settings and then switch them to either 32kbps-128kbps. That would compress your movie. I just wrote that in case you don't know since you're still learning.
