Skeleton Model Shadows on Classroom Blackboard Mazatlan

Bright midday sunlight streams through a high skylight, illuminating dust motes above polished concrete floors and rows of wooden desks. A white plastic skeleton model stands upright near the front, its rigid bones casting sharp, elongated shadows that stretch across the dark green blackboard. The light highlights the texture of the chalk dust on the board and the smooth grain of the desk surfaces. Along the walls, deep shadows define the corners of the room, showing stillness. Books lie closed on the desks, their spines catching the glare. at the edge is the precise alignment of the skeleton's shadowed fingers against the rough chalk surface.
