The way you use microtonality, dissonance, and the time signature to support the narrative is super creative, in addition to sounding cool! I also like how each track has it's own stages and progression on top of the overall ost progression. I think Apotheosis is my favorite.
side note- on the youtube playlist the tracks are in the opposite order than you listed here, not sure if that's intentional but I listened half way through the wrong way before realizing
