To me, this is a study of two pieces of art. One from the poster artist and then the scene to the left as captured by you.
My first thought was to have a picture with just the poster. But, then, that would be simply a capture of the work done by the poster artist.
My next thought then was to reverse the composition so that the poster would be slightly out of focus and the single lady with the bag would be sharp and clear.
The cerebal artistic connection, on the right, of a woman with child, with a single women on the other side would still be intact.
By the way, I also liked the poster being in black and white as it finds its way to contrasts with the color on the other side. This of course re-enforces the subjection of the two sides, imaginative and reality, in your wonderful composition.
