Wow. Great image. I'd like to see a version where the red-tone would match in the doorway and the sign, and the figure would be sharp, but under the circumstances, you made a very atmospheric photograph. Isn't photography 'illegal' in the red light district? I remember reading that it was a good way to get yourself beat up and your gear taken away.
the softness of the male (it seems) silhuette removes some emotional impact from the photo from me. It is well conceived and executed, but what is the figure doing there? partaking in solace providing by the bordello? working in one? I am not sure what it the point you are trying to make, hence a high, but not perfect rating, and a somewhat ambiguous feeling
