Your worldbuilding in this through you instrumentation choice was really cool, and you had some super out of the box harmony choices that took me a second to get used to but honestly I love it (swimming upstream was my favourite, it took a bit to click but it was my favourite). You Should be proud! I would say to maybe experiment with drum samples a bit as these ones felt a bit... piercing? Something thats a bit more deep and less resonant might help a bit, but still excellent work.
