I really like how she is both monochromatic with the background (all the way down to the hair/forest darkness) and yet separate. Nice cohesive composition of outdoor plus undoubted emphasis on the model.
Image by Nick Knight. I like the organisation of this image because the material is being pressed onto the subject creating light structured shadows. The high contrast in the background is bringing out the shape of the subject creating boldness by hiding its identity. The black and white are blending together creating light and dark grey tones to add a mixture into the image.
