I thought I commented on this. Not really sure what the scale is. At 4:17, in the original track, I hear three chords play. It's sort of a subtle glissando. That may not be the correct musical term. I guess you can say the notes are a tad more humanized rather than three notes pressing down at the same time. So I wrote out what I hear, and maybe you'd like to throw it into your remix. Someone with a better ear could probably tell you the correct notes. I'm not saying yours are wrong. In your remix, you only have the final note being played, which I believe are A, E, and then D.
Overall, I like the direction you took from the original. It still has that qualm feeling. This Divine Beast was one of my favorites, as well as the boss, but I felt unsure of what I was supposed to be doing.
