Robot retro sobre metal con grafitis en ciudad distópica al atardecer

A retro-futuristic robot with a worn, bulbous head and oversized, round eyes stands atop a metallic chassis, covered in vibrant graffiti-splattered panels in faded sunshine yellow, sky blue, and fire engine red hues, set against a gritty, dystopian cityscape at dusk with a low-hanging, fiery orange sun and a backdrop of sleek, high-rise skyscrapers.
