      "description": "Based on <User Portrait>, a young woman standing on a rustic wooden rope swing in deep snow, head gently tilted to the right resting against her gloved hands gripping the rope near her face, eyes softly closed with a serene peaceful expression, subtle smile, long black hair falling naturally past shoulders with gentle waves",

        "expression": "Serene contentment, quiet joy, as if savoring the cold mountain air"
      },
      "pose": "Standing upright on wooden swing plank, both hands in white knitted gloves gripping the thick hemp rope at face height, head tilted right resting against knuckles, left leg extended slightly forward on swing edge creating a gentle S-curve in body, right leg supporting weight behind, torso slightly leaning into the rope — a relaxed yet elegant standing-swing pose"

      "framing": "Near-center composition with subject framed between two vertical swing ropes creating a natural frame-within-frame; three-layer depth: FG = snow footprints and texture, MG = subject on swing, BG = snow-capped mountains + blue sky + wooden village fences; subject occupies ~60% of vertical frame height; adequate headroom above, swing plank fully visible at bottom",

        "highlight roll-off: very soft, protecting white detail in snow AND clothing simultaneously",
        "shadow tint: neutral to very slightly cool blue",
        "contrast curve: low contrast — must differentiate white-on-white (warm cream clothing vs cool blue-white snow)",
        "grain: minimal to none — clean high-altitude light",
        "white balance: slightly cool (5800-6200K) to preserve snow transparency, with skin tone compensation"
