I really liked this a lot. :) The only thing that kept you from the 10 is that you should filter the non-piano sounds to a minimum so that the piano can come out more...it would sound more dramatic and chilling. It's still a great piece of work though...hence the 9.
Dunno what to say xD
But i liked it alot :P
