How to Build Good UI? What is Your Workflow?

I have been using Cline with grok code fast, Almost for 6-7 hours straight building a webapp.

I have built couple of decently complicated projects previously but one thing that I always don't get good is design,

I have used ShadcnMCP and couple of other UI libraries but still it doesn't feel like the best or something out of the ordinary.

I have seen some fellow vibe coders building Framer/ Figma level UI/UX on their webapps.

How do u Guys do it? What is Your Workflow?
