For hotness you need big breasts, ass, and personality.
All of those things are illegal and politically corrected in western media of any kind. Breasts and ass? That offends twats, which you idiots gave rights to, and personality? Female Characters can behave in the most horrible of ways and yet never suffer consequences. Yeah, that's attractive NOT!
Also western art styles are generally ugly shit like Grim Adventures, Invader Zim, Samurai Jack, etc.
