On this piece I like the background, it reminds me of a timeless old-fashioned country scene from one of the great pictorialists. I feel the gentle contrast between the blacks and whites, and also the desaturated tone gives the model a lifeless feel. I admire the uncomfortable position of the model which creates a sense of submission.
If you look deep into the photograph you can many layers, the longer you look, the more layers appear. The way the layers are used on the model forms a ghost-like spirit. Finally, I like the mystical feeling it creates of the soul emerging from the body.
