Not bad

Daemon? This is a boss battle against Matt Daemon isn't it! I knew it!

Just kidding...It sounds pretty good for a boss battle, so I think you captured that atmosphere really well. I could definitely see this in an RPG game for a boss battle, maybe not the final boss, but a mini boss for sure.

As far as things to improve on, the percussion here comes off as a bit generic sounding to me, but I think you could turn down the volume on it a notch as it seems a bit overpowering at a few certain parts.

As far as the main melodies, I really don't have much criticism for them. I think you actually constructed those quite well. The song itself is nice and lengthy too, which is always a good thing to know you put in the effort. The multiple melody changes are nice to hear.

Overall it doesn't strike me as anything really catchy, but I think it's a good battle tune for sure. Keep up the good work.
