animal ears,, Cat ears are fine, though I wouldn't add it to design if I had a choice but like, those horse ears (?? those big floppy ones) seem to be super popular? and I just, don't get the appeal at all... Also characters with a human face, but then neck down/waist down there's fur or some pattern or smt. SO they just have human skin face (and torso), and yeah. These are just personal ticks, no particular reason lol
also just designs that I just, can't tell age at all, especially due to body proportions. They can be 14 or 25, who knows. I mean, it kinda comes with the popularity in anime-ish art styles and how those rolls, so I get it, but still, not a huge fan if I had a choice.
