I think the instrumentation and storytelling work really well here, there's a good progression in energy between each song that hits the vibes you're going for. The minor piano and sustained instruments give it a floaty feel, which works for the wavy, peaceful but scary and mysterious oceanic setting. The foley sounds like the waves were really great for adding atmosphere, but I think something to experiment with would be to keep the wave and foley sounds a bit more consistent as it sounded a bit sporadic. Overall great stuff!
