Create an ultra-realistic urban background scene featuring an old

Create an ultra-realistic urban background scene featuring an old, weathered concrete wall with visible cracks, chipped paint, and rough textures. The surface shows signs of age and decay, with patches of darker discoloration, dirt, and erosion. Faint turquoise graffiti covers parts of the wall, painted in broad, uneven strokes that contrast sharply against the gray concrete. The lighting is soft and diffused, evoking an overcast day in a cold city alley. Subtle shadows fall along the rough surface, emphasizing depth and realism. The atmosphere feels gritty, industrial, and cinematic — as if from a modern spy thriller or neo-noir film. The composition should capture the detailed wall texture and urban mood with photorealistic clarity, high contrast, and natural color tones.
