FFX - Seymour Battle, Mario Paint

This is the battle theme from Final Fantasy X that plays during the final fight against Seymour inside of Sin.
This was done by ear from listening to the OST. This one's been the most difficult for me to do so far...XP
I think one of the most interesting things about the original song is the choice of instruments used; the limited choice of instruments in Mario Paint kind of handicaps the song. =P (The most prominent one is that there's no 'crashing cymbals' percussion sound). With what I had, this is what I was able to come up with!
Let me know what you think!
Also, by request, I've uploaded an MP3 file for this song, which you can find here:
