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.", "composition": { "framing": "subject centered, snow angel wings fill most of the frame, lots of clean negative space snow", "camera_angle": "high angle, diagonal perspective, boots closest to camera", "detail_focus": "snow texture + jacket fabric + face clarity" }, "styling_notes": [ "keep the snow angel shape crisp and believable", "keep clothing consistent with winter gear: puffer jacket + snow pants", "no extra props, no extra people" ] }, "negative_prompt": [ "extra people", "extra limbs", "deformed hands", "extra fingers", "blurred face", "face swap artifacts", "identity drift", "cartoon", "anime", "cgi", "beauty filter", "plastic skin", "over-smoothing", "text", "watermark", "logo" ] }
