Awesome! Very characterful, and nice to hear a different energy in contrast to the more obvious approach of stillness and space. Very dense writing with loads of interest, but it conveys the frozen character really well and the sustained level of detail allows it to fit into the category of ambience I think. In the right type of game this could be very appropriate music. Listening-wise personally I found it a bit overwhelming at times, but in-game where it's lower in the mix it could be really effective. I would say the mix is slightly over-compressed for my taste, it's harsh on the ears in places and would benefit from being allowed to breathe a little.
