Wow! I really enjoyed how this piece develops (with the 3 movement structure). The cello motif in section 2 and 3 adds some interesting dramatic contrast to the otherwise evil sounding accompaniment.
If this were in a real video game, it would be cool if that cello line had actual significance to the player. Making it’s appearance in the boss fight that much more emotional.
Also I love how well the first section with the percussion/piano hits captures that impending death aesthetic!
