On the horizon the city of Valladolid partially hidden in the middle by a hill located between the city and the viewer.
I tried to simulate a waterfall of lights by the way of moving down the camera backwards which requires a precise and steady movement to keep verticality and a correct exposure.
I am not satisfied with the results at the moment but I will repeat it again and again.
Concerning postediting I applied a too evident blurring spread filter over the "waterfall", and placed the moon cutted from another part of the shot in a layer with diffuse blending mode.
