Ron - Thanks for the kind words. I agree and also prefer the first one (p.1128 #15 ) — it's the contingent nature that I like about this picture. For example, I tried cropping to the bottom of the woman's foot (which cuts some of the space on the left of the frame) and straightening the frame so that the U.S. Army Never Let lettering becomes horizontal and the edge of the shop building becomes vertical — but this rectilinear approach makes the frame more static and loses some of the feeling that you refer to.
EDIT 31-Jan-2015: After writing the above, I went back to the second mannequin picture (p.1129 #5) and concluded that the crop that I had done, after reading someone's recommendation, which placed the man in the center of the frame made the picture more static. I now have gone back to a slight modification of the original. The man is now off-center and I feel the picture has more visual interest, and becomes less static, with the light area restored in the bottom right of the frame. One has to look for a while at a picture before concluding on a final version, but often the first instinct os the right one, as in this case.
