How's my face meshes?

I’m trying to improve a few of my models, and I noticed that they still have a bit of the ‘uncanny valley’ effect. I’m also having trouble making then more gender specific. What can I do to fix this?

Left to right, the faces are male 1, female 1, male 2, female 2.

Hi there, if you ask me it’s the anotomy that lends these wireframes an adrogenous look. Just study some anatomy. You can study it by looking at medical references, or just by looking in a celebrity magazine or the people around you.
Study the effects that various arrangements of attributes can have to the impression that people give you when you see them.
