Your compositions are always great, and this one is really not obvious, which is not easy in such a "strict" challenge. I like the dark tone of the track, but I think that the mix is a bit too dark. The composition is enough to give a feeling of despair, and the loud low-end makes it a bit too dark. In fact, my favorite part begins at 0.52 when you're playing more in a high register, but remaining dark in the mood
