This is a beautiful soundtrack. All the sections have their own characteristics, but it all sounds like one cohesive world. The pizzicato violins in particular gave that section a distinct atmosphere. That said, I would like a bit more variety in the different pieces, to really give the feel that I'm traveling to different environments.
The violins panned hard-right were a bit distracting to me listening on headphones.
I'm not sure how the looping would work in practice, but I'd be very interested to hear it -- it's a cool idea.
Great work!
