Shot in gritty, high-contrast, black-and-white cinematic noir style with a shallow depth of field, a diminutive, rusted robot, adorned with flickering neon tubes and exposed copper wiring, perches atop a hulking, armored cat, its fur a matted, metallic mesh, eyes aglow like hot coals, as it prowls through a ravaged, post-apocalyptic cityscape, amidst twisted, blackened skyscrapers, shattered neon billboards, and tangled, sparking power lines, beneath a sickly, yellow-green haze, illuminated by the faint, fiery glow of a dying sun, with crumbling, graffiti-scrawled walls, and rubble-strewn streets, littered with shattered machinery, and the skeletal remains of once-majestic buildings, all set against a backdrop of perpetual, smog-choked twilight.
