Hmm
This sounded a lot like one of Yann Tiersens songs. You should hear that guy, I can't remember what the song is called, but you use 50% of the tones in that song :p Ah I can see a reviewer has mentioned the song too. Comptine D'un Autre Été it's called. Try to hear it, and compare these two :) But this song is still original, and I like the instrument you used.
