figurine is currently an ambiguous mess, and I'm not sure how to go about dealing with it.
First of all, the alias figure attracts mistags from people trying to tag various body types, figure skaters, etc. But beyond that, there's a couple different things in this tag:
Figurine concepts
Figurines for tabletop games
Model kits (model_kit)
Anime figures (anime_figure)
Miscellaneous plastic toys
There's also miniature_model which from the wiki page I'm not really sure what it's specifically supposed to mean?
I do think a catchall umbrella tag is handy, such as "figurine_(object)", but I think the 3d renders/art that are just concepts for figurines should probably be under a different tag instead? "figurine_concept" or "figurine_mockup", maybe?
