Very nice! Reminds me of a mixture of Swans and the ambient/experimental tracks Bowie made with Eno during his Berlin era.
I think you've managed to create a lot of depth with a few well picked elements. The arrangement flows seamlessly. Nothing screams for attention, yet it never gets boring.
The mix feels even and nice, love the drums. Great dynamics, really serves the piece.
There's a little grime that really adds to the mood, can't really put my finger on it though.
Great job!
