It's hard to think of a more striking bone structure than Ms Weeks's.
These low-res video grabs still give an idea of her fantastic jaw, and the astonishing way it interacts with her equally strong cheekbones. Look at the scooped shape of the underside of her cheekbones and the way its shadow/depression extends beside her mouth. A very graphic kind of beauty - she's like a stunningly attractive line drawing.
Oh and her lips are rather luscious too - nicely offsetting the rectilinear aspect of her face with some softness.
