This is a truly beautiful photo. This is a great example of how different textures can make a black and white photo stunningly vivid. For me, black and white is all about showing off contrast and texture, and this photo does an awesome job of that.
I love the contrast of light and dark in this photo. I also love the symmetry that the shadow creates (a line down the middle of her face) Also, I love close ups on emotion, this draws in the audience and makes them feel the emotion.
