A nice piece of work
Every now and then I like to come back to the audios and try to put down some comments to help people so here is my two cents, take it or leave it.
What you have here is a very nice piece of work. I was surprised to find that it really seems that the piano takes a side seat to the strings. While you see this kind of an effect not many times do you see it keep that consistancy throughout the piece. You will find solo moments for the piano to flurish but you dont seem to have those moments because you seem to let the strings build the mood and the scene which I think is done correctly and with very nice precision in this instance.
Through out it, I never once found myself thinking, oh heard this part before, you have a nice solid motif but it isn't one that is beating the listener over the head, it a nice reinforced theme that carries through the piece nicely.
I will also compliment you on your use of chords. You have chosen some strange times to resolve on chords, that gives a kind of haunting lilt to it, almost a minor key it seems.
Overall, an amazing piece of work that is really top notch.
