Me too. I cross out in my mind any that have been done, but there is one I saw in a competition (that did badly) that I absolutely want to see how it was done. It was in Leadenhall St, corner of Lime St and somehow Willis Towers curled over Lloyds. I simply can't replicate it with any lens. But mostly I look for lines, reflections and context, so more documentary and less about juxtapositions.
