Good sync and good flow with the music.
But... I mean, conceptually, I've seen this kind of AMV countless times. Then again, it's hard to make FLCL unique anymore.
But I did like how you experimented with the frame sizes and used some of the effects. Especially at around 1:31. THAT was really nice.
I'll add this to my FLCL folder. I dug it, and I can recommend it to people that like FLCL videos. Still, it's a 5/5 because it was just a really solidly edited piece.
