Yes, I try to line up landmarks in the photos with the 3rd marks in the photo. Photo 6 leads the viewers eyes away from the central part of the post and out of the frame. The lines travel in many directions keeping the photo interesting. Photo 1 has repeating triangle shapes that travel backwards through the frame. Photo 5 best captures the essence of an empty playground, to me it feels begging to be used. I also like the changing background and shadows.
