Establishing reference photograph of a place: 2D hand-drawn illustration, wide low-angle view inside a grimy subway tunnel looking up a vertical concrete ventilation shaft. Heavy iron grate torn open from inside, bent outward with jagged sharp edges, fresh scrape marks scoring the concrete around the opening. Faint pale daylight spills down the shaft as god rays through drifting dust particles. Deep surrounding shadows, stained damp walls, rusted pipes, high-contrast lighting, threatening investigative mood. Empty scene, no people, no text.
No people, no visible text, no watermark.
