it's cool
yah, it's cool. I like the composition and everything. The music video synced well with the song. My suggestions though:
next time don't use shape tweens unless you want to change the color of something, because their obvious and I don't think they look that good.
Never have a plain white background, because that tends to make the movie look unfinished.
Lastly, and this has nothing to do with the animation so it doesn't influence my score, don't immediately bring up your age. It isn't going to cut you any slack. XD
But know really, I think it was cool. I loved how the fire flies made a little person who hugged that guy, it was sweet. Sure hope to see more from you because you have QUITE the potential . :P
