i think the issue with the eyes is, first, you have the eyefolds down so low that they make an unnatural crease at the inner eye corner, and second, the outer edge droop is probably slightly over exaggerated. I get the duck lip thing, but i would say once again, that the problem isn't the type exactly, as much as the degree of exaggeration.  i think the new renders are a big improvement, would just say you need to darken up the lashes. make sure the gamma is set to one on the trans map, and maybe a touch of displacement.

other than that, if i was you, i would move on. take all the comments good and bad, look hard at your work, turn your pictures upside down,& flip them horizontally, literally, and see if things still look natural, then move on to the next project. this might not have been the success you wanted it to be, but don't get trapped into endlessly trying to fix it. make a new one, start from scratch. i have done things i thought looked amazing, then seen them 6 months later and been horrified. not saying that is the case here, but am saying you will get more out of moving foward than getting stuck on "fixing" what you have already done. you asked earlier about rendering hair, am sure there are many far better suited to give advice but a very slight amount of translucence, set at the colour of the hair your rendering(ie light browns/yellows for blonde etc) can make the heavily contrasted shadows much less, and less fake looking. i use about .05 on the translucence value. if you overdo it it looks bad.

anyway, good luck.
