I would think that eyebrows are purely a guess if the remains are skeletal. I know that there is a skeletal basis for determining the placement of the bottom of the nose (the partition of the nostrils is called the columella), so I am not so much concerned with the shape of the nose as I am with the positioning of the columella, the width of the bridge and the shape of the triangular area above the bridge (called the glabella).
They say that you can tell from the skull whether or not the columella turns upward, and the length of the columella (and therefore the prominence of the tip of the nose) is determined by a specific ratio with respect to the small pointed bone at its base (called anterior nasal spine). I have read that the positioning and width of the mouth is determined by the gumline and the canine teeth. The top of the upper lip lands approximately at the upper gumline, the bottom of the lower lip also is positioned at about the lower gumline, and the corners of the mouth are placed at the tips of the canine teeth. However, the thickness of the lips is a guess (based on averages for the person's ethnicity).
As for this Jane Doe, the one thing I am looking for when browsing for possibles is the tiny chin, the absence of cheekbone definition, highly positioned columella and high forehead. Angela Finger fits all of these criteria (setting aside whether she is a strong possible on other factors).
Liehnia Chapin looks fairly close on the cheekbones and forehead, but IMO she has too large of a chin, and her columella is positioned too low.
