Technically I think it's nicely done. A good selection of instruments and nicely understated. However, two critiques. 1) It runs a little too long and starts to become tedious around the middle. Perhaps you could edit out a stanza or two? 2) A lot of different styles but kind of meandering. It's a nice piece of ambient music but I'm never exactly sure where it's going. Perhaps a bit more structure in the organization of the piece would help?
Anyway, my stuff is full of technical errors and I know I should be the last to criticize, but this piece, if reworked, would be a nice addition to a compilation CD.
