Solo piano using just a soundfont, hmm? Sorry, but this doesn't work for me. I like where you're going with the arrangement, but when you synthesize a piano you lose the expression that a real player gives it, and in solo piano music that expression is much more important than it is in other types. Play with the velocity controller some (which you have at points, it could just use a little more work), especially in the beginning (I would suggest taking the intro a little slower than the rest of the song, too).
Also, I noticed some clipping at points. It's not as bad as I've heard in other songs, but if you do nothing else to this before you re-submit, re-record it with slightly lower levels.
NO, but it's almost there!
