Really agree with the view that this image is probably one of the best photos ever made. Simply fantastic usage of available gear at the time, and fully intentional in rendering. It would be tough to criticize the image at all, except maybe that it remained relatively unknown for such a long time.
What amazes me is the relative lack of progress of so many photographers after the time of this image. While we obviously have many great photographs that come after this time period, there are rare exceptions that express a scene in a uniquely photographic way. What I mean by that is had an illustrator or painter been near that seen at that same moment, the resulting image would have very likely been quite different.
