Hmmm, Change the Advent Children clip, it looked out of place among the anime, also, add some kind of transition between the clips, some where ok but the last few jumped, you may also want to fade out the end and shorten the last clip and put your credits in as it ends.
Good choice of clips, it was pretty epic.
What is that song by the way? ive heard it before but cant remember what its called. :dead:
