Wow.
One of my favorites in this challenge. Surprisingly, it didn't had that WOW effect when viewed as a thumbnail. The others were a sure favorite from the start.
Centered compositions are usually not that appealing to me, but this one is different. The leading lines from the rail, the sidewalk and the buildings, the beautiful B&W tonal range, the wide depth of field (or is it called a deep depth of field?), the emotion and the power of the kiss, all these elements just work together. And the fact that the whole scene i stilted a bit doesn't bother me at all (it usually does). It might even add to the whole experience.
