Very nice piece of music.
If I may offer a criticism at all, it would be that the string figures heard at 0:46 and 1:17 are a little odd sounding, but I'm not sure why. I think at 0:46 the rhythm played is just a bit jarring, and at 1:17 they could be brought up just a bit to punch them through because they make a musical statement that is worth hearing.
Thank you for putting up your list of materials; that is exceedingly helpful in understanding how you created this. Excellent.
