I don't think the common definition of "Visual Arts" includes Artisan Crafts, so that subcategorisation is misleading for the user. If you look for example at the wikipedia page for "visual arts" the subsections are drawing, painting, printmaking, photography, filmmaking, computer art, plastic arts & sculpture.
However if you separate arts and crafts at the top level alongside each other you run into the problem that people won't easily know where to put the three-dimensional fannish arts, because few of those are the traditional sculpture, but more often things that people associate with "crafts", like fannish dioramas, where dioramas are a typical thing people associate with school crafting lessons, or modified dolls and action figures (rather than sculpting from scratch), or really modding stuff in fannish styles in general.
But that is better than to put all crafts as a subsection of visual arts, I would never look for it there.
