Establishing reference photograph of a place: 2D hand-drawn illustration of a dark, cavernous industrial facility interior, wide eye-level view. Massive pipes snake along the walls and ceiling, with rusted metallic structures, catwalks and riveted beams fading into deep shadow. A heavy armored sliding door stands fully closed. Dim light comes only from sparse flickering industrial lamps and faint neon-blue indicator lights glowing on machinery, casting cold blue highlights on a grated metal floor. Mysterious, atmospheric mood, inked lines, textured shading. Empty, no people, no text.
No people, no visible text, no watermark.
