Some people think that taking a nude picture of a beautiful woman with the emphasis on the usually covered body parts is nude art. But this photograph takes in the body as a whole and still draws the attention to the expression on her face while it is not in the foreground of the picture. I still would have added this one as a favorite if I could only see her face.
The little tension in her body seems to me like she was startled of a wild deer or something behind her, which is quite a nice effect, it's not dangerous at least. It makes you wonder what she is looking at. The way the hands are together makes it more likely that there is a person though, like there is some interaction and an emotional connection with whoever it is.
