Well, I'm not sure what to say. On one hand, it was awesome. On the other, it wasn't very good.

I thought the effects and sync throughout the whole video were awesome.
And the slow parts of the song were amazing, better than I've seen in many videos. Very dramatic.
But the fast parts felt really lacking. On top of that, I didn't like the song much at all (except for the slow parts), so I'm sure that's a part of it. It wasn't that the flashes got annoying, because those didn't bug me in the slightest, it just felt really lackluster.
On the whole, I'd say it's a good video. The clip selection was great, and you pulled off the concept perfectly. However, the fast parts bring this video down a few notches in my eyes. And, yeah, they are good for contrasting the slow parts... but I still didn't like 'em.

You still remain one of my favorite editors. ^_^
