A very atmospheric piece that transitions between whimsical, eerie, and doom-laden seamlessly. The compositional skill here is evident. Excellence!

The dark atmosphere in your intro is perfect for a boss fight lead-in. I love the piano melody that comes in at 0:29, as this really sells me on the Halloween theme. The intense drums and organ work so well together to suddenly jump into the intense beginning of the fight. The transition into the second part of the song is very well done and feels really big! Following the big crash is a section that is a little more subdued than I expected, but that seems to make the boss feel a little more creepy and works really well for the spooky intention. Great work and thank you for sharing!

Very foreboding. The burst of organ runs was a highlight for me, a personally would have liked more it.

I really liked the composition in general. It has a dark and intriguing atmosphere. It looks like you put a lot of effort into it. Congratulations

That was really cool! I like how it builds up to the organ and horns towards the beginning but then it goes back to being sort of subtle and atmospheric. There's a lot of cool subtlety to this piece where the instruments come in to play small parts to add to the spooky atmosphere.
