Under the umbrella - night HDR photo

I really like shooting night HDR landscape photos (like this or this). They are so different from sunsets, sunrises and blue hour shots everyone is used to nowadays. When I shoot them I try to find a very dark place but with some strong light in the background. It creates strong and often surreal effect. Also by using long exposure I bring a lot of details to these very dark scenes. For instance I shot above photo from a place where I could hardly see anything (even my camera) close to me - it was so dark. But by using long exposure and high ISO I "restored" a lot of the scene.
