Had a little bit of sunset tonight, but as the sun got close to the horizon, a line of clouds moved in and totally blocked out the sun. Fortunately, in the direction 90 degrees away from the sun, these clouds lit up from the sun. Sort of funny seeing everyone getting pictures of this and not of the sunset in the other direction. Best in black if you have the time.
An old sage photographer once told me, when you see a great sunset or sunrise, always look behind you, because there may be an even greater picture there. Looks like your image is not far from that adage! Verrrrry niiiice!
