This feels like an orchestral suite as it transitions smoothly from one theme to the next. The pulsing strings and the use of organ gives this an ominous and dark feel which fits your story well! I appreciate how you add layers in with each repetition so no section ever feels exactly the same as the previous section. After such a long track, I was expecting a build-up to a bigger ending, but I still really like all that you have. Thank you for sharing!
