A couple of suggestions
First off, the "Play" button needs to be disabled after the viewer clicks it once. I shouldn't hear the opening guitar bit if I click it over and over. Second, I'm not going to critique your art. I'm sure you know it's not stellar, but it's better than half the shit coming down the pipes. Third, when choosing ambient sound effects for the background, try to choose sounds that blend well with each other and themselves. Every time you looped your background sound, I heard, "Sooo, tell you what..." Gets kind of annoying and kills your atmosphere.
Cute story. Not the most original, but short and simple. Keep practicing with flash. Everybody's gotta start somewhere.
