Pasillo Frío con Casquillos Esparcidos

Photorealistic cinematic low-angle shot down a long, empty [modern gray office corridor] with a cold dystopian atmosphere. The camera rests near the glossy polished stone floor, using dramatic one-point perspective toward a dark vanishing point at the far end. On the left side, tall frosted glass windows glow with soft, overcast white daylight. On the right side, plain concrete-textured walls feature a dark doorway recess, a high ventilation grille, and a gray utility cabinet. The ceiling contains five bright rectangular fluorescent light panels receding into the distance. The polished floor shows crisp, elongated reflections of the lights, windows, and walls. Scattered across the floor are five red-and-brass [shotgun shells]: one sharply focused in the extreme foreground bottom-left lying horizontally with its brass rim toward the camera, one in the right midground near the wall, one in the center midground, one further back left of center, and one tiny shell in the distant center. Shallow depth of field, subtle floor dust, muted slate-blue color grading, cinematic atmospheric haze. No people, no blood, no text, no watermark.
