Prompt
Create a wide 16:9 layered-paper artwork of one future green city seen from a low aerial angle. Build a clear vertical garden corridor from foreground parks through midground streets to three tall smart towers in the distance. Place rooftop gardens, hanging vines, and one elevated pedestrian bridge along that corridor, with metallic gray interfaces kept secondary. Use torn paper layers, visible cut edges, moss green, clay, cream, silver, and deep forest shadows. Keep the skyline sparse and readable, with nature as the main visual path. No text, logos, watermarks, or random towers.
