Lol, there might as well be.



Ehhh.... I don't think there is any indication that the person in this picture being non-human gives her any non-human anatomy besides having horns and scales. There are certainly cases where non-human characters that happen to be humanoid will have very tiny waists and it will make sense, because that is how their species should look, but I don't think that's the case here. This girl looks very much human in pretty much every way and it pretty clear that she is not meant to have fantasy anatomy besides some horns and stuff. Even if this person is meant to have an unnaturally thin waist because she is not human, it still wouldn't really... Work. That works with humanoids that are far removed enough from human beings so that they don't just look like people wearing horns with some scales glued on. Those types of humanoids typically do not have human skin and instead have skin that is an inhuman color and texture, as well as anatomy far removed from the typical human being. This is literally a human being with some stuff added, and thus if she is meant to have a very thin waste, it would just come off as disconcerting and strange looking. Plus it would still probably stem from the artist's idea that women with nonexistent waists are meant to be attractive.



Although, that being said, a humanoid that looks a woman with a disturbingly little waist that is a deconstruction of art like this could be a good concept, if used to highlight how off-putting this kind of stuff looks and how it would be very unnerving to see IRL. But I think we can all see this person just thought the thin waist made her look pretty, or attractive.
