My personal impression of Weston was that he was a human being first and a photographer second. The pursuit of his photography was the means by which he explored and also expressed his humanness in the world about him.
Weston had a "life view" not well aligned with the traditional "Christian majority" of the segment of the world that he inhabited. I mean this not in a derogatory sense. What I mean by this is that Weston was well established in the belief that all things are interconnected and the individual "things" merely representative "particles" of a much larger all inclusive "whole". I would take it that from this orientation that to Weston a dead man in the desert was as much a part of this realm as a nude, a pepper, shell, or a mexican woman grinding maize.
On the basis of composition, this photograph with it's diagonal orientation of the subject creates a sense of energy and tension in it's own right. A noteworthy thing, I think...considering Weston's view of life.
