Interesting view of 'prison' if that's what this is. The ceiling/roofing isn't exactly solid looking and the dark image would probably be better if your darks were even darker. I think more contrast would help set the mood.
Nice take on the challenge. Sounds obvious and cliched but this works well with strong lighting and composition. There's possibly too little detail however (more prison-liker context would be good). [9]
My favorite picture of the challenge. The Black and White really helps to set the mood. The contrast, Shadows and angle of the picture are perfect. Excellent shot. Good luck. 10
I like this a lot. The contrast is great, the depth of field is perfect, and the use of line and shadow really brings the image together. Well done. 10.
Stark, evocative, graphically strong, great focal point of the trees outside. Wonderful use of strong light and shadow. Great composition with the negative space towards the lower left.
Great shot ... I like how the top and right side are lit, and the bottom and left side are dark. creates a lot of tension, which is good. Good luck. Jacko. 9
