Thank you

Right! It quite from the character generator. Because there's no suitable man's face in the DLC of I bought, so I make some man's face
The most important thing for the face is "Expressive". They're just a template for “Expressive”.
You can reference them to make some interesting face at the character generator
The above is Machine Translation ^_^

I agree wiht you, some of htem are okay, but suddenly they change eyebrows? wth

This is simply just faces from the character generator...
And the characters look inconsistent.
