The piano is nice choice for an icy aesthetic, very clever. There were a lot of good choices made here, like the reflective, quieter part that brings the piano back. The key change was also really cool, the track was really effective at building intensity and had a good sense of tension and release. What the track could improve on is the balance, I feel the drums (especially the snare and hi-hat) were too loud and took attention away from the melody instead of supporting it. I also think the guitar at the beginning was too muddy mix-wise. It might've been how distorted it was, but i think some EQ or panning would help it not to clash with the bass. Great job!
