Awesome work!
Each piece felt unique but still cohesive, which I think really helped distinguish each chapter of this story. My favorites were probably the Savage state and Destruction, because I felt they were especially fitting and executed for their respective sections. To me, Savage state feels like the beginning of an adventure, and Destruction feels like the whole world is falling apart around the listener.
I also liked how how the motif was used in the Pastoral state as well. This was a nice change from the previous piece, and I found it helpful in pushing the momentum in the story forward towards the Consummation stage.
The choice of french horns to bring back the motif in the Desolation stage was an excellent choice. I'm not sure I quite heard the happy it happened vibes from it - for me this was more of a remembrance, like this is the end of our story. Also, I would have liked to have heard that final chord be a little stronger and more drawn out to really assert the finality of it, but that's more a personal preference.
Thanks a ton for sharing this, keep up the good work :)
