I like the idea here though I feel like it would fit better with a more spooky/mysterious theme. I can hear the underwater inspiration there but when I look at the smiling girl and bright colors in the picture theme, I don't hear this. The track is mixed really well though; nothing jumped out at me and it sounded smooth throughout. I enjoyed the steel drum section the most as it felt more connected to the theme. Overall I'd consider rethinking some instrumentation choices and add more layers and mixups in the beat to keep the track fresh and interesting throughout.
