I really love the tone and concept of this game! This is like, a genius use for these assets. I think in terms of critique, sometimes the ui bugs out, specifically when looking at the palm trees. Also, you should unify the fonts (sometimes you use the default unity arial, but other times you use the included font).
Without asking you to go outside the restrictions of the prompt, I guess I'd love to see more of this little world you've made, like short, snarky bios about the artists, or little quippy responses once you give them a comment. Maybe that's out of scope though, I don't know.
