How about small button style noses?

That boils down to if they look like a human with a button nose or if the button nose makes them look inhuman.

you like anime faces where they often don't even have a nose?

Kinda, not most anime faces but something like below

Would you be considered attractive by most people?

Plain is thrown around a lot.

Actually, I'm curious if you could post the "least unattractive" guy or gal you have ever seen in your eyes.

Don't really keep tabs on people I find unattractive because there are so many of thembut some celeb examples are Rihanna and Henry Cavill, face wise I find them uncanny.

You said most, but that's not all.

True, I'm more engendered to people with faces like Willem Dafoe, Mark Hamilton, Diana Swole, I'd say Clancy Brown too, but only when like 30- 40% of his face is obscured by the brim of his hat. I'll also say that the autism isn't social skills, but the peculiarities of the fact that I've people in hijab and abstract mask the are devoid of most human facials features and I know I'm attracted to that, thus anything not that is unattractive even if I'd consider it more attractive than other certain facials features
