Establishing reference photograph of a place: 2D hand-drawn illustration of a long high-tech corridor, wide shot from a low angle, polished metal floor reflecting pulsing red emergency lights mounted along the walls. At the far end, a massive heavy metal blast door hangs partially open, beginning to descend, its gap glowing faintly. Sleek silver wall panels, black shadows, strong one-point perspective. Red, silver, and black palette, tense atmosphere, clean ink lines with painted shading. Empty, no people, no text, no sparks or dust.
No people, no visible text, no watermark.
