The work extends from a drawing of an aerial city view made from the top of a mountain. It is a parodical comparison between satellite and celestial views. The idea that somebody/something is watching from above at all times triggers the use of non-photo blue color, suggesting a map or object that is not interested in being found or reproduced.
