This is a great example of how to do an under the train shot. Great color, great depth, great lighting, and interesting composition with the rail coming at an angle from near the lower right corner like that.
A very unique look at the challenge subject, this is nearly perfect in every way. Both a technical and artistic success, this static view from a unique perspective is unchallenged so far in being inventive. Crisp, sharp with well controlled bokeh, this should be a ribbon winner. Very well done.
