well it must have worked because he's a bit off kilter in the first image and he's much straighter in the second. it's interesting that he chose to do it in the street. the light and shadows and the surrounding buildings make these shots really interesting.
this one took me a minute to figure out what was going on. at first, i thought i was looking at a tree in front of reflections on glass, but i finally worked out that it was a top down view of a pond. really interesting photo.
