Establishing reference photograph of a place: 2D hand-drawn illustration of an empty derelict U-Bahn station platform, cavernous interior with rusted steel pillars receding into darkness, shattered white wall tiles, abandoned benches, debris along the platform edge beside dark tracks. Lit only by flickering cyan emergency lights mounted on pillars, casting long creeping shadows. Cold cyan and deep shadow palette, low-angle wide view, eerie sterile atmosphere, inked linework with textured hand-painted shading, no people, no text.
No people, no visible text, no watermark.
