I Call BS
There is absolutely no change in dynamics or tempo the whole song and you claim you played this by hand?
This version of the battle theme is off of the Final Fantasy VII Piano Collection, of which I have both the album and the actual sheet music. I've been playing playing piano for 17 years, 13 of which with lessons, and I've played this song out of the book. It sounds like you tried to translate the recorded version of this song to midi by ear, because many notes are incorrect. The tempo is too perfect to be human, and a trained pianist would never play it so rigidly, anyway, particularly the middle part which is supposed to be more gentle. Lack of dynamics could just be because the keyboard isn't pressure sensitive, so I'll give you that one. If you did play this by hand, it was done very slowly with a metronome and sped up later, though there's still a heavy reverb on the notes, so I doubt it, unless you added it later.
Therefore I think your claim that this isn't sequenced (MIDI) is BS.
You get a 3 since copying this by ear would be difficult. I'm assuming you didn't have the sheet music in front of you when you put wrong notes in.
