Very nice textures and mood Tim.
I think at times, there is too much conflict between piano and flutes and even cello at times.
I don't know what to focus on when I am floating along with the piano and then the contra melodies come in.
Maybe they are mixed too hot? Or maybe in mixing, instruments that are featured should have more of the spotlight?
Anyway, I think you did a great job with the arrangement. I really love the piano melody.
