This really isn't my area buuut
In number two have you possibly gone a little too far with her face? Might not just be the editing, but also the rather flat light over her face that is adding to it; but it just looks so alien plastic looking. The eyes certainly look like you've boosted the whites considerably, whilst something is really looking odd around the lips and teeth (lack of shadowing I think is making it look like her lips and teeth are flatter than normal).
She just has that plastic "deer headlights" appearance which I find offputting.
Of course I respect that this might be your intent, but if not maybe some easing off from the facial editing might be in order?
