Very intense and I love the creativity with the crow.
I think your own criticism of the sporadicness of the piece is interesting. I don't think a piece necessarily has to flow between each section, as it depends on what the piece is going for, and only you the composer know what is right and wrong. Making a chaotic piece can be easy but making a good chaotic piece that still has some structure is hard. In this case, I think you managed well. If you wanna work more on getting a better flow/transition between sections maybe try to change your composition process. Of course, I have no insight into your process but instead of working with fills as transitions have some long notes carry over or add a bar and two to make a transition.
I think this could fit very well in certain games/scenarios.
Overall very good and creative!
