This photo uses shadows to add contrast. The shadows also give the illusion that the woman's eyelashes, lips, and no are larger than what they really are. I think the photographer wanted the viewers to feel empowered by beauty and to be larger than life.
A very interesting and somewhat new concept of portrait photography that shows the model holding up a frame, only to reveal the back of their face. It gives off a strong anonymous identity that makes you want to be able to physically walk around and see their face.
