How can I effectively use perspective in comic book backgrounds to create a sense of realism?

Perspective is crucial for creating depth and realism. Use one-point, two-point, or three-point perspective to depict buildings, roads, and other objects receding into the distance. Pay attention to vanishing points and converging lines. The size of objects should decrease as they get farther away, and lines should converge towards the vanishing point. Consistent perspective is key to avoiding a distorted or unrealistic look.
