The exceptionally elegant and robust face of model Brenda Schad. The bone structure is so developed that the face seems full of bumps.

Notice the perfect equilibrium between over developed cheekbones and jaw angles: cheekbones are where the jaw muscle attaches: large cheekbones = large jaw muscles and thus large ramus surface for muscle attachment.

A face is a highly functional chewing pressure mechanism. 
High efficiency is translated by our brain into beauty appreciation.
