I love negative space in this picture. It makes this self portrait more beautiful. The contrast between the woman's face with the black background gives the photo mystery. Also even though more than half of the photo is dark, it still has an overall good balance.
One of the most evocative contemporary photography series I have seen in a while is Michael Wolf’s Tokyo Compression. The German shoots people in the subway trains of the Japanese capital. The result is breathtaking: an emotional collection of commuting individuals, with each portrait telling a unique story.
