That higher saturation color treatment gives this place a new life, a new vitality to this old place. Very interesting contrast too, how the contrast is different in different zones, and how the zones make transitions across the frame. [the flatly contrasted second flight of stairs, versus the extreme contrast in the lower middle of the shot, for example]. Very nice work.
Oooh, Stairs make neat pictures. You got a good angle. Lighting, color, and texture make it interesting. I'm faving this. This looks like something that I would love to paint in watercolor. Would you mind if I used the pic for a painting reference someday? (I'd credit you of course for the inspiration)
