The newly added Pinned Collections feature to the Home page is nice. Along with the Pinned Models and the Recent Models, they provide a good introduction to a desinger’s work. (although I still prefer to have models shown in sections like what MW landing page does instead of having models inside collection folders)
To encourage/nudge users to visit the designer’s home page, I would suggest that when a user clicks open a model, a carousel of other models that are in the same collection from the same designer be shown at the very bottom of the page, after the rating section.
Related models from other designers would still be shown on the right side of the page.
