Camera Work/Technical: I like the crisp focus on the lamp. It works well to pull the eye right into the image. I would like to see a bit deeper depth of filed to include some of the floor detail in the foreground.
Lighting: I also like the lighting. I do find the lone highlight on the left side of the image a bit distracting. The rest of the image is nicely lit.
Composition/Content: Nice composition. The lines of the blinds as well as your shadows work well with the focus to pull the viewer's eye into the frame.
My Opinion: I think that you met the challenge well, but you were lacking the needed pop to separate this image from the rest. I believe that the voters found that the challenge was met, but the content was a bit too commonplace.
Shot from too low of an angle for my tastes, I am not fond of the OOF floor in the foreground. But not too bad overall, good lighting, very clear, nice tones.
