A bit slow-paced (heh, what more can you expect from "Nothing Else Matters" LOL) and the music and the scenes sometimes didn't match. I liked the ending with Inoue and Rukia though. Heh, an experiment is an experiment. It's always nice to play and mess around with what you have until you figure out what would be the best to use such things.
Here's a tip: Subtitles are an eyesore and are distracting. Unless the context of the subtitle fits with the song or the AMV as a whole, any unrelated dialogue is just distracting and doesn't let the viewer relate with the song and the scene. The viewer is busy reading the subtitles sometimes. Editing out all the subtitles is hard work and finding raw episodes is even harder so it's not really necessary. It just makes things look a lot nicer.
Good AMV though. Keep up the good work. It takes a lot of practice and a lot of patience.
