This one is a bit different. In fact, the larger version doesn't really carry a great deal more detail than the thumbnail. So I think this is very effective full size because it's simplicity is maintained. The image is about light, line and form. The man in the lower right is sometimes often not even noticed until the full sized image is viewed. This, to me emphasized the point that little things make all the difference. In this image it's the inclusion of a "little thing." In most images, (like the one above) it will be the removal of the little distractions that makes the image successful.
