Establishing reference photograph of a place: Classic cel animation style interior of an empty speeding metro car, lit by its own fluorescent ceiling light strips casting even cool-white light. Closed sliding doors with a colorful metro line map mounted above them. Rows of empty plastic seats, metal grab poles and hanging handles. Windows show a dark tunnel rushing past with motion-blurred streaks. Clean ink outlines, flat color fills, simple cel shading, painted background, no people, no text.
No people, no visible text, no watermark.
