Very cool! The high notes at the beginning (and the end) made me think of the Disco Elysium main menu theme, and they had the same quality of being a premonition (and then a memory) of an apocalyptic event, or of a world that is simply indifferent to the fate of humanity.
I'd agree that the mixing could have been better in places (particularly in the Consummation section, I think). On the whole it didn't detract from the enjoyability or the fascination of the music, though.
I found the Destruction section the most interesting. I felt you took a different approach to most in the Destruction part, and it works really well. But my overall favourite part was the Savage State. I liked the simplicity of it and the sense of pathos and anticipation in that slow build-up. Nice work!
