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.
Mouth of Flower - Octavio Ocampo This is good art because it is an optical illusion. It could either be just some flowers with a butterfly, or you can also see a womans face. It is very creative in a subtle way.
