I don't get how you don't get this in such an aggressive fashion. Let's say you (or the person who commented originally, if that's not you) really can't see gain's art looking human. Setting aside issues with that*, then instead of criticizing "big-nosed, bee-sting lips" why not be a little more careful with wording?* Saying something like "noses and lips that are so exaggerated as to be unrealistic" makes what you're going for more clear / might avoid the microagression that comes from sounding more like, regardless of whether or not you think it, that big noses and lips in general are "hideous".

* wtf. stylized art is stylized?
** seriously. that's all I was saying.
