Good detail, good subject. I feel torn, though, between the cold (tungsten WB?) of the cell interior and teh warmth of the door and wall. If all was so cold, I would have felt absolutely hopeless.
I like the slight peek inside to see the skeletal bunk of an inmate from yore... Exposure is good but the scene is somewhat bright and lacks good lighting conditions for that extra emotional content.
I don't really get any emotion from this image. It's setting (a prison cell block) should give off a somber and dark feel, but the colours and processing negate those feelings... so I'm kind of left with nothing.
