Oooooh! This is cool.
I can understand why you would be concerned with realistic piano pieces in your other thread. In all honesty, it sounds like a solo piano piece to me. Almost reminds me of C418's remix.
I'm getting some distortion all throughout the song. Of course, I have crappy headphones and a loud speaker.
The measure of the same note(s) at :16, :24 was a little unnecessary IMO.
At around 2:24, when it gets soft, I honestly thought you were going to do either the Song of Time or the Call of the Giants from Majora's Mask.
GREAT START! I might comment later as well.
