Thank you Sam.
I actually, was thinking that window-like frame is the source of light.
I did not increase contrast by post-processing, I pushed darks down in Curves. I maybe wrong but I think the contrast "inside" the dark areas (walls) did not change but the pic as a whole gained more contrast.
The one of the reason that in this Moriyama's photo "... even in the dark lower part of the photo, we're still experiencing such a sense of light." but not happens in my one is that the rich texture of the walls ( in compare to Moriyama's) on my pic grabs the viewer's attention and prevents analyzing the impact of the light, in addition to the wall's limited "real estate" to record the complete fading of light on the walls.
