The music box plinky sound is way too loud at parts.. Im sure you noticed, but shouldn't be hard to fix for a big improvement.
I think the piano with a bit of a thick reverb so it sounds more sustained would be cool, and it would also make the song flow better in my opinion.
I think you should keep working at this.. hopefully there isn't a completed version on your page that I've missed. :P
With some smoothing up, this will be a pretty neat song.
Gave a low overall, it IS incomplete.
