Thank you! I am glad others enjoyed it.
It was a fun evening with two friends. The shot was actually significantly past the blue hour. It was taken at 11:50pm, and sunset was 3hrs prior.
I used tungsten white balance, 25s exposure at 1000 ISO, with aid of the nearly full moon.
Much of the shoot we were stumbling around in the dark, as none of us were bright enough to bring a flashlight.
Next night shoot-- scouting during daylight, cable release and flashlight.
