Beautiful, and very well-composed!
Ah, finally, something original on the audio portal! (All those crappy game midi uploads ripped from vgmusic.com are pissing me off.)
Firstly, it's a very well-composed piece. It could potentially bring tears! The arrangement itself is ALMOST there. Needs a little more work to really evoke the sadness from your audience. Sadly, this piece is really only marred by the low-quality samples. But that can be easily fixed with a really good piano soundfont! :) (Or you can just record yourself playing a real piano)
Overall, great job! Can't wait to hear more from you! :)
