Cool selection of sounds.

This is a cool ambient track with some interesting effects on piano, and I'm liking those pizzicato from....is it a violin? I'm not sure, but...it's cool.

What I think you need is some more reverb to make it sound a bit more "full". The instruments themselves do a lot to keep the song interesting but...it wouldn't hurt to add a few more effects. Maybe add a layer of crescendo-ing strings, perhaps just EQ the timpanis.

This has got potential, keep it up. :D
