I've seen worse quality, and on files three times larger.
The video's competently edited from a viewer's standpoint, but there's not much of a story there and the link between the lyrics and the video is kind of vague sometimes. Suggestions? Plan your vids better in future and try to detach yourself when watching what you've already edited. And get rid of the damned subtitles.
Also, I don't know how many AMVs you watched before joining the org, but find some good ones you like (and some you don't like, because that way you won't be too busy watching them to pay attention

) and try and figure out what makes them tick.
