If you continue to study actionscript and actually get a real version of Flash (not some shitty poser version), you could make such great stuff.
First of all, the animation was...not great. Work on that. A few extra frames here and there can significantly raise your score. Secondly, use movie clips. That's what they're for. Using one timeline is too confusing and is asking for potential bugs and glitches. Finally, it needs more interactivity. I've never used SWiSH but my friend has it and claims it's shit, so maybe it's time to switch to something a little more capable of making professional material.
P.S.:
Stop using the "make your own movie before rating mine" excuse. A critic doesn't need to be a director to know a good movie from a bad one.
