so, like landing page would have a horizontal list of new pictures posted by users you follow (if you're logged in) followed by all new pictures underneath in a grid. A tag page would have the top X favourited pictures for that tag at the top, and then a grid of all the pictures below it. Page for a picture itself has the picture itself in a ~ 3/4 screen width column with the remaining space for a card of the user who posted the art, and under the picture is the picture title, description, tags, and any comments left by other users. User page is essentially the header for the user, and three tabs -- one for the profile information and grid of latest pictures, one for all their pictures, and one for their favourites/bookmarks.

Pixiv has some things where you can add your own tags to other people's works, as well as story publishing, it also divides art posts into "illustrations" and "manga" but honestly I feel that's an artificial distinction. I know the tagging thing isn't doable as just a Pleroma frontend, it'd need its own AP activity to be supported anyway.
