Empty background for a 2D survival cartoon: an abandoned ruined city street after a disaster, broken windows, an overturned car, scattered trash and debris, a fallen street lamp, smoke rising in the distance, an orange evening sky. No people, no blood, no text. Composition: the upper third is calm smoky sky, the lower third is clear empty road. Muted brown-grey palette with orange accents, soft vignette. Same drawing style as the attached reference: 2D cartoon, hand-drawn look, thick black outlines, flat colors with simple soft shading, no texture. Vertical 9:16 (1080x1920). Keep all important objects inside the central 80% of the width.
