The shadows on this image look like they are being reflected from some sort of blinds/windows. the fact that the photo is black and white it makes the shadows and light on the persons body stand out a lot more with a really good coordination of stripes.
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.
