the first problem is the theme, the first part doesn't go well with the rest, I'm sure that the track would sound better without it. That leads to the second problem is that you have a happy melody over a dark-ass intense drop. I recommend using the harmonic minor scale.
But anyway, I like how you compressed the distorted Reese bass, it sounds very loud, but it doesn't crash with other instruments, and that is what I appreciate. Various dark percussion, I'd say this has some potential to be in a Madness Combat animation lmao. I like the transition to the drop as well, before there was a tempo change, there were glitches.
And as always, I like having a calm outro after a hard-ass drop, like you've beaten the final boss and now you can go home.
