I, for one, don't feel any wish for either more or less included in the frame.
As I look at it this time, it reminds me a bit of some of Karin Rosenthal's photographs of nudes reflected in tide pools, where the nude figures take on the texture of the rocks. Here, the rocks suggest (to my mind, anyway) a human form. But the nice thing about the image is that I can play with it and imagine all sorts of things, and yet all my interpretations seem to share a quiet, contemplative mood.

P.S. Dare I say it? I think Minor would like it, too.
