Woww, thank you so much!! It means a ton to hear you think this kind of piece could improve the soundtrack. I'm a big artcore fan, so I'm really glad 'change' was translating well for you, with my studying of it.
I have to agree, about 2:17-2:20, actually I was going to calm things down at 2:10, but decided to add an extra section to risk overcomposing for sake of learning and experimenting. It's neat you noticed that too, I think it would've helpd the song. And great suggestion on stacked 4ths, will keep that in mind.
