Avoid the appearance of any modern elements that are out of harmony with Lima's historical and cultural aesthetics, such as modern automobiles, contemporary signage, or modern infrastructure that does not integrate harmoniously with the historic urban environment. Exclude any form of environmental pollution, such as garbage in the streets, smog over the city or visible sewage, to maintain the purity and natural beauty of the environment. Do not include elements that may suggest extreme social inequality, discontent or tension among people, in order to preserve an atmosphere of harmony and joy. Avoid depicting buildings in a state of deterioration or abandonment that contradict the sense of care and pride in the cultural heritage. Also, exclude any type of problematic urban fauna, such as rodents or large numbers of pigeons, which could detract from the vibrant and clean urban scene.
