I... haven't watched this anime. >.>
But I get the general gist that a girl dies and then something happens.
Anyway, I thought you had the "cutting in offbeat ways to maintain interest" editing style down pat.
But it got a bit repetitive - as in seeing it over and over reduced its effect - so things you could do to break the monotony? I noticed there were zero effects in it - anything basic (except I generally hate it when a basic effect is used throughout the AMV - remember, we're trying to break the monotony) - and with the weird colours when she's falling in that clock thing, you could have changed the hue so it's different. The other thing is that there's an almost unwritten rule that you shouldn't reuse footage, at least too often. Maybe your hands were tied in this, but at least try to do something to the footage to make it a bit different.
Also, visuals were weird, so that was interesting.
And I liked the music - kind of grand with the woman singing loudly - fits the grand theme of... whatever the plot is in the anime. <.<
