Composition is nicely written, atmosphere well established. I would pull that whistling wind synth down some, also the high string swells, until the piano gets more established like at 1:30. I still feel it's quite loud there. As subtle as this piece is, it's very noticeable if anything is even slightly out of balance.
I may also clean up that reverb some. The low mids 250 hz and below are ringing out and resonating when you have low strings or other synths and not contributing to the space so much as making a little extra noticeable fuzz.
Otherwise, really enjoyed the piece. Great work.
Thanks for coming out to NGUAC!
