City in the night. Ciudad en la noche

This digital painting is tricky and it´s influenced by my research on urban morphology. Seen from a satellite, the cities show areas of different colors with more density, usually called ¨urban sprawl¨ or in Spanish, defined as ¨manchas de aceite¨ (oil stains). In this case, the clusters appear to be in a desert land with spots of water, like some areas in Peru, for example. But the light color in the edge of the sea is tempting us to look at the picture as a ¨vertical¨ landscape, being the sea the blue, the stains with lighting an urban horizon, and the rest, a dark-brownish sky. We can read it both ways.
