One thing that is wild about this song is that I never really knew what to expect. I kept on getting surprised by what's coming next, even though I can't really explain why. I really like the sound, it's very tense! It really builds up a lot of dread and fear as it goes along.
Though to be honest, when I see the Pumpkin King I think less of the tension of dread and fear, and more something like an intense kind of horror.
Great job here, this is pretty solid!
