A very evocative track Pete, I was seeing cold blue shades as I played this!
The instruments and arrangement sound fine to me; and for me it leans more to smooth jazz than New Age. With that in mind, if I were mixing it I think I would bring the drums and bass forward a tad, there needs to be a little more anchor in the bottom end to contrast with the sparkling sounds higher up. I'd ease off the reverb a weeny bit. Oh, and here's me being a bit OCD, the end fadeout needs to be long to suit the mood of the piece maybe? But that's just my ears!

Off for another listen...
cool
