Conjure White Walls

I like this very much. The curves in the buildings and the blurred clouds suggest the geometry of flowing water - in fact at first glance I thought that's what it was.

All those open windows and the general absence of any sense of action below the clouds give it a slightly eerie feeling, and make me wonder if the site is abandoned, or if it was just one of those moments. And it's always interesting to have nature presenting itself as more animated than the expected human bustle.

The very sharp edge of the rooftops of the center two buildings give it almost a cel-shaded animation kind of look. I don't know how much you actually did any processing to sharpen it, but it's a small thing that adds a lot to the contrast.
