Yes, I think that the gender and race of the ears doesn’t always match. Maybe gender is the wrong word, but some ears look too delicate for the individual or something. I’d never guess these were fake if I saw one by itself though.

Yeah, I didn't spend as much time studying ears as I did eyes in art school, but now that you mention it, I see it.

Most of the "parts" of the face look like they've been clipped out of a magazine and photoshopped on. There are subtle errors in orientation that don't match the head's orientation. It makes the overall head look flatter than the lighting on the face would suggest.

Incidentally, I work in VR, and mismatch of depth cues between color and position are things that can cause simulator sickness.
