This is my original image. I liked the shadows and lines but beyond that I found it uninteresting. There is no point of interest.
I decided to give the girl on the right a greater role. In cropping I sacrificed some of the lines of the shelter in order to get in close enough to give the girl some prominence. I brought up detail in the foreground and blurred it in the background, and changed the opacity in the upper right to give a backdrop to the girl.
