The focus of the image is the setting in which the image was taken. A large portion of the image is the setting, and not on one particular character/object.
A woman and a baby is sleeping on a pink piece of cloth laid out on the ground outdoors. They are sleeping in front of a metal grill. Bright pieces of cloth is hung onto the metal grill. They are faced away from the camera. Their clothes are ragged and dirty. Their surrounding too is not that clean as well. It seems to be in a dump.
I think the story that lies behind this image how the woman and her baby is forced to live on the streets because she is poor. She neither has proper shelter nor does she have proper hygiene, due to her living conditions.
I think the message that the photographer is seeking to convey through the image is how people are living in poverty and are forced to live on the streets. Their living conditions are terrible, as they have no choice but to make they do with what they have (which is not very much).
What I like about this image is how the photographer managed to capture the whole scenario very well, and it depicts a very obvious story.
