Tiny little too much verby verb on that piano, also saxes are terribly hard to make sound good even with the best VSTs, I recommend swapping it in for a flue or clarinet, as what you have written is a bit low for saxes, and listning to the rest of the track, I really don't think the saxy harsh tones suit the breathy, light style of the track anyway.
The writing itself though is wonderful, even if a little bit difficult (though still possible) for piano. I myself am bored of people writing totally impossible to play piano music thinking it's awesome when anyone with a trained ear can hear how difficult it is. This piano writing in this has a lovely waft of 20th century minimalism.
Personal preference here, I absolutely despise pan-pipes, not that anything is wrong with how you implemented them though. All too new-agey for me. Swap em for strings IMO.
Wonderful none the less, 5'd!
