The chaotic energy you were going for. I think the rhythmic crow cawing was an amazing addition, and the movement the way you panned it was cool. I think if you automated it, that could create a sense of the crow flying around. The electronic tone colour works really nicely with the theme and the percussion is so detailed. It contributes to the chaos of a boss fight really well.
Love it when you have that contrasting section with the crows and drum roll. It's a nice way to break up the piece . If you added some more contrasting material might make this a bit more interesting over time, especially with the context of video game music. But I think this is really cool overall, nice work.
