Anthrofying anthro characters:
Characters that are normally already considered anthro may still be included, but only if they are drawn in a manner that's considerably more human-like (still) than usual. Think overall body proportions (this is especially noticeable for characters with a chibi-like build) as well as things like gaining plantigrade feet instead of digitigrade, human hands instead of paws, wearing clothing...
Where exactly to draw the line for each character may be a bit subjective and based on intuition, as well as how humanoid they already appear in basic form, but perhaps these examples will help you get the general idea:
Note that all of this only goes for actual copyrighted (franchise) characters, not your regular anthropomorphic furry. They should just be tagged anthro.
