Establishing reference photograph of a place: 2D hand-drawn illustration of an empty neutral digital void, seamless grey-toned infinite backdrop with no visible horizon, subtle soft gradient from pale grey to muted brown near the floor, faint flat ground plane with a gentle shadowless sheen, flat even ambient light radiating uniformly from the void itself, clinical technical character-reference atmosphere, medium low-angle viewpoint, clean ink linework, flat muted grey and brown palette, minimalist and sterile, no people, no text
No people, no visible text, no watermark.
