Lucy Liu, sharp jaw angles
Luc Liu definitely has a sharp jawline, particularly in the region of the jaw angles.
B+ jaw angle grade, and B chin grade.
On the picture where she is smiling, you can see her teeth. This kind of teeth shape is typically feminine in their roundness. Any good anthropologist can determine the gender of a skull just looking at their teeth.
Her teeth are a slightly too big in my opinion, probably because of a ceramic coating.
