FFVII: Advent Children - One Winged Angel, Mario Paint

This is the version of One-Winged Angel that plays in the movie, "Final Fantasy VII: Advent Children".
I've always wanted to do a version of OWA...so here it is!
This was done by ear, by listening to the OST. This is the longest song I've done so far, and it's taken quite a while to finish, too.
Note!
There are a few moments where I improvised the piece, which are the solos that happen in the song--the two main moments are the first solo at 1:05, and then the 'transition section' that has completely new material at 4:27. I decided that I wanted to create solos unique to this version (and that's partially why it's taken so long, though actually, I've been kind of busy, too...)
In any case, let me know what you think!
