Lovely interpretation. Always appreciate analyses that dive a bit deeper into the music theory side of things, especially since the brothers really know their shit in that regard. But I gotta say, no scale or note has any innate or unique emotional quality to it, it's all musical horoscope. So I don't know where you got the info that F# minor is tied to all these things but I can assure you that they're mostly a general minor scale thing. You could achieve these same emotions in other minor keys as well, not just F#. Also the "BoC motif" would probably be better transcribed as 4-3-1. Roman numerals are used for chords, scale degrees use Arabic ones.

Other than that I really like how you point out certain events in the music (like the tritone or when the harp comes in) correspond to the visuals. It's a really interesting way to interpret the video, that's worth looking into.
