This is very nice modeling TVeyes. I will not even show you my attempt at the eyelids until I can get the side view right (side view tells the whole story) and you got yours right on.
Skin tone: I like her skin tone a lot, but, not knowing where the light is coming from, I assume she is facing it directly (as that is what it seems to be), I think the chin area and jawbone on the sides of the head should be a bit darker skin tone for shadowing (looking at frontal view) like you have the shadowing done on the top of her head at the sides.
And one thing just as a sugestion, but not a 121. But if I had her, I would just try one thing to see how it looks. I would mask off the eyes and below, and a part of the eye brow, the part nearest the nose. Then, ever so lightly, I would move the top of the head on some (with symmetry), remove the mask and see what you think. There may be a “line” from the move, but if you cannot get rid of it in two smooths, then go back to what you had. I have found that if you do more then two smooths, you usually create more lines that need to be smoothed. But if you move the top part of the head in a big bit, then try it again by moving it in just a tiny bit, and I think this will also help with your eyebrows (which you think are off).
But I have to say, this a damned good model, and I cannot wait to see what the rest will look like. She is wonderful. You really should name her, you know
