ripples in the surface of a body of water

Imagine a vast, calm body of water under a cloudy sky in stunning 4K resolution. Suddenly, footprints begin to appear on the surface as if an invisible figure is walking across. Each step presses into the water, creating sharp, detailed ripples that expand outward, disrupting the serene surface. The footprints are crystal clear, with realistic splashes and water displacement, as if real weight is pressing down on the surface, but no one can be seen. Tiny droplets sparkle in the high definition as water clings to the shape of each sole for a brief moment before flowing back to fill the space, only for another footprint to appear just ahead, continuing in a slow, steady rhythm."
