One woman lies on her back making a snow angel, arms extended outward and slightly blurred from motion, legs spread comfortably. Snow is piled around her arms, hips, and legs, with clear swept-wing shapes and scattered powder. She wears a light silver/white puffer jacket, black snow pants, winter hat, dark gloves, and light-colored winter boots. Her face is visible and joyful, looking slightly upward. Snow texture is highly detailed: powdery surface, footprints and small scattered clumps around the angel. The camera is angled from above at a diagonal, creating a strong perspective with the boots closer to the camera. Realistic motion blur only on the moving arms, everything else crisp. Premium photoreal look, no stylization.",
