Window Over Red Sunset

Full size. On Flickr.

I like this picture.  The amount of blur in the background brings out the clarity of the foreground - more specifically, the various bits of dirt on the window, as well as little water droplets.  Despite needing to be cleaned (don't look at me, because this isn't my window), the window is actually quite clear, so all of these things look like they're floating.

I could also point out the vignetting, but that will feature in the next image.
