Might be better to use a song that somehow follows the game through it's lyrics in one way or another.  Machine head doesn't fit KH2 at -all-.  Amvs should usually take weeks or months to work on, an hour or more from each of those days.  And using the same clip twice in one amv isn't such a great idea either ^^;  I'm only telling you this to help you get better, not to put you down or anything.
