I love it. The black and white is perfect for steel and stone. It reminds me of industrial age to 1950s images. To me, the photographer looks more like a piece of sculpter that might have been placed there.
Nice work as usual. I like this effect from SilverEfexPro. On my monitor there's just a hint of mixing of "cool tint" and "warm tint". I think whatever you label it, the overall effect is very nice in this mixture of stone, glass and steel. Also great job with the sharpening. Just on the edge and just right, it makes the details pop and the separation of the stairs and ventilation grate is "great" .
Roger It's still, ISO, aperture and shutter-speed, right?
While the focus, exposure, and composition are dead on, I find the b&w rendering to be very busy. I would love to see what the color version looks like to help separate the photographer from the stairs.
