Comet Crossing a Giant Clock

A photorealistic scene of a colossal antique clock housed in a vast cathedral-like chamber. The massive brass gears, polished steel escapement, and ornate Roman numerals of the giant clock are exposed through a weathered glass face. A bright comet streaks across the scene, its icy tail glowing blue-white as it whips through the open clock face, scattering light on the inner workings. Sunlight filters through high windows, creating volumetric beams and dust motes around the gears. The hands of the clock are paused as if surprised by the cosmic visitor. Ultra-detailed macro shot of gears, jewels in the movement, and the comet’s tail crossing the dial; 8k realism, HDR lighting, cinematic atmosphere.
