I like this one a lot. The B&W format allows the viewer to focus on the lines of the picture and less on color. I wish I understood what that squiggle at the left was.... an electrical line?
I am going to step out a little here. The main subject, the window with bars is good. I like the reflections of the bars in the glass, and the vague view of the interior. I like how two worlds merge in the glass, a sort of shot I also use. But, to be honest the surroundings just kill this image for me. The top right is a mess. The plants not so bad, but why? I do not see that they add to the image, and of course, the bit of mess on the wall, well that cannot be helped and should be left in, but the pipe work? no. A crop tighter on the window to remove the extraneous surroundings is a little tight with regard to the window, but you need to keep the angle on the window which is good. An alternative would be to go right into the window itself.
I am probably going on a bit here, but I like your work and I am trying to be constructive. If you want me to stop I will.
