Wow.
This is great, it all perfectly went into sync, really nicely done. I think you'll pass lol.
The effects with the made images out-side of Flash, the clouds and stuff, was a cool effect, atleast you didn't try to do a bad drawing of clouds.
I liked it how the blue circles came in, with the music, they went out, also with the music, it was a nice touch, but the only bad side was the length, it was good for a class project but not really for the portal. I like to sit there and enjoy a nice music video, which this was, but as I started to relax.. it finished. Haha -.^
There were alot of images made outside of Flash, which was mainly it's flaw for the portal, but not for class.
I think it's perfectly in sync, and it really captures the atmosphere of the song with this Flash. The guitar 'solo' was a nice touch to liven things up a bit, and were everything came in and out with that so perfectly.
I think you should make another one, but way longer, really long. You see how high the score of this is now? If you make it longer it would be even higher. ;-)
