The dying of the light

At the end of the day at daylight's last gleaming the prosaic can become interesting. This is such an example. A cloudy evening and the sky just lightened for an instant because the clouds lost their homogeneity and a brief cone of light shone on the top of this otherwise dull building making what I think is a nice shot possible. You have to be at the right place at the right time and must be ready with your eyes and your camera. Who said it was easy; actually it's not too hard.
