Camera Work/Technical: Great focus and very interesting depth of field. I can also tell that ht WB is spot on for this scene. Really nice exposure control, keeping the details in the highlights as well as the dark areas.
Lighting: The lighting here is a little distracting. The eye of the viewer is initially drawn to the bright area beyond the hand. Cropping that out would have improved this photograph tremendously.
Composition/Content: Your subject is a bit small and too centered for my personal taste. I'd like to see the bright wall cropped out, and that would make the composition even more interesting. I do like the busted window that you chose for the natural framing of the shot.
My Opinion: While it loosely fits the challenge, it is not what I had in mind for an environmental portrait. My opinion of an environmental portrait is a person immersed in their work or play environment, looking at the camera with some sort of expression that is noticeable. Perhaps the firefighter standing at the window, or close to it, with his arms crossed and a dirty face. Even with that opinion, I think that this one would have scored higher with a little tighter composition. Overall, nice work, and being a long time paramedic, I always appreciate nice photos of public safety.
This is a very interesting photo, I love the shapes/colors and the broken window in the foreground is a nice touch... I am having some difficulty seeing how this shot meets the challenge - but I do like (very much) the abstract quality.
