I'm prepping for a client walkthrough and want the UX mockup to feel more like a real product experience without over-investing in clickable prototypes. Any tips for structuring mockups for maximum impact?

Totally hear you—and Clay’s breakdown on UX mockup design is a must-read. They show how to bridge the gap between concept and execution, focusing on how mockups can simulate a user’s path through the interface in a clean, visually engaging way. It’s especially useful when you want to sell the feel of the experience without building a full prototype.
The article covers everything from fidelity levels to visual communication strategies, including how to use mockups to tell a story—ideal for client-facing presentations. It also touches on tools, layout patterns, and annotations that help reinforce your design logic. If you want to leave clients with a strong impression of both aesthetics and function, this is one of the better guides out there.
