This part while sounding more energetic than the chorus and the intro is quite a downer when you compare it to the intro which was harder than this section, I suggest just keeping the 4-note chords and deal with jacks somehow, so it doesn't feel disappointing to play.

Why was this sound omitted here, yet it wasn't in the "Hard" difficulty? I suggest adding a note here so that it's consistent with other difficulties.

This instance is a 3-note chord in "Hard" difficulty, you should make every accented vocal syllable a 3-note chord just to really accentuate the vocals and differentiate it from other vocal syllables.

Considering this sound in the "Hard" difficulty, it seems like you're not representing it as well as it should've been. This cymbal has a 3-note chord in the "Hard" difficulty yet in the "Insane" difficulty it's the same as the kick drum sounds despite being more loud, I suggest making it either a 3-note chord or a 4-note chord, whatever you prefer. This applies to every instance of the cymbal crashes.
