I like the cute synth riffs at the beginning and the dreamy pads. The progression and sound design are both really satisfying, and I can hear the influence of the mermaid theme. It's a smooth-flowing and well-structured piece overall. You say it's part of your "fast-paced rhythmic stuff," but I think a lot of melodic came through rather well here. My main complaints include the lack of more legato-y elements in the texture, and also a missed opportunity for a stronger climax towards the end of the piece. Overall, though, this is a really fun piece with some glittery synths and catchy rhythmic elements. Keep it up, EndK!
