Loop isn't quite perfect, but very beautiful piece. No comments on the playing/writing -- pretty spectacular to me. What you could do to make the loops seem more natural in the future is take the excess sound after the point you intend to crop and hang it over at the beginning so that it fades into the piece -- sort of as if you'd stepped on the sus pedal and started playing the piece over but kept the second run through, if that makes sense. I do that with my loops quite often.
Stunning work! I look forward to hearing it in use!
