I do like this picture, although what another photography said, there is too much middle grey. (or something like that) i think that contrast could have been better. maybe not have the entry light on?
I do like this shot over all!
I'm going through the entries, stopping at those images I feel have had the benefit of an unconventional eye and dwelling a little longer to try to see and appreciate what you saw. This is one of those images.
Positives: Great moody image - bring your own story stuff. I really like the POV and the use of the straight lines.
Critical stuff: I'm not a fan of your conversion, I think a stronger contrast treatment might have been better - the grain too, enough to annoy but not enough to delight.
Overall: I really like the idea but I'm not sure this is an optimal edit.
