◇ Could this help me?
Yes. Gathering concrete visual references before building is the practice that most reliably lifts a generated interface out of the default look, and browsing a curated gallery is about as low-risk as advice gets. The three named galleries are ordinary public sites, so nothing here needs to be installed or gated behind a message. This is a general practice.
I am going to paste in links or screenshots of designs I like. Analyze them and produce a reference brief I can build from: the color palette with values, the type choices and their relationships, the spacing and layout rhythm, the motion behavior, and the three or four specific details that give these designs their character. Then tell me which of those choices are safe to imitate and which are specific enough to that brand that copying them would look derivative.
