For me, this photograph is all about composition. The symmetry is outstanding. There are differences, of course; it is not perfectly symmetrical, which I think is better. Perhaps the most striking aspect of this photograph, for me, is the expression on the models' faces, one playful and one more tense. This creates a kind of almost subliminal tenses which suggests the post cannot last, that one of them will "win," or perhaps neither will win in this battle of mock wills. Wonderful work. Zenmatt
