bedsheet ghost as gallery guard

A single bedsheet ghost stands upright on a polished concrete floor acting as a night guard in a minimalist art gallery, creating an elegant, quietly eerie mood. A slow-moving bat pattern from a projector washes mottled shapes across the sheet and floor, suggesting motion and calm suspense. The sheet is plain white cotton with subtle midweight folds and a tidy hem, and the floor is smooth, glossy concrete with faint wear and micro-polish reflections. A nearby placard is mounted on the wall reading "HAUNTED GALLERY," with a reserved blank panel beside it for a tidy headline that remains unlettered and visually balanced. Lighting is soft and flattering with gentle separation and a calm, low-contrast grade that reads cool overall. Mentioned hues appear: navy slate for deep shadow (#0f2333), soft white for the sheet highlight (#f5f7fa), concrete gray for the floor tone (#9aa0a6), deep charcoal for accent planes (#1f1f23), muted teal for subtle color cast on the plaster (#5e8b8b), and pale lavender for the faint atmospheric wash (#d8cfe8). The gallery interior feels spare with a single clerestory suggestion and a small track of visitor absence, and the scene includes a minimalist bench and a low pedestal as props. The placard is matte metal, centered at eye level, legible contrast against the wall, and the headline panel stays blank and unlettered. Frame the composition in a vertical 2:3 crop with the ghost slightly off-center toward the lower third, leaving clean negative space above and to the right for poster or copy placement. The view is eye-level, normal field, showing the sheet, floor reflections, and wall placard clearly. Rendered as a high-detail commercial still with crisp material realism and subtle cinematic color grading for an ad-style photograph.
