Interesting concept just using simple loops, then adding sax lines of different intensity. Along with the use of effects.. My one complaint, buts its more of an opinion, you could have tried to tell more of a story with the sax.
I Like it just as it is and generally prefer it when the music isn't about the player and has a life of its own. Jan Garbarek certainly plays in this style, but a guy named Paul Winter was more specifically playing with natural sounds in this vein back in the 1960s. Your playing has more joy than Garbarek's (who is also one of my favorites) but he has much darker tendencies.
Nice one Davey
