Medienhafen Light Painting

One chilly and windy evening last autumn I grabbed my camera and headed into the Düsseldorf harbor (Medienhafen) to experiment with some light painting techniques I learned from a wonderful local photography group. I probably could have benefited from arriving at my destination with a little light left in the sky, but sometimes it's just fun to shoot when the mood to take pictures strikes. I like the glossy effect of the water and the twinkling stars in the sky. Can you spot the smiley face in the fourth picture down?
