      "description": "Based on <User Portrait>, a young woman hair falling past her waist, sitting curled up on a concrete curb, head tilted slightly to one side, hair cascading over her shoulders, arms loosely hugging her knees, an introspective posture with a gentle smile",
      "features": {
        "hair": "hair, natural waves, cascading freely over shoulders and face, catching warm ambient light on the edges",
        "eyes": "Visible, bright and soft, reflecting the gentle smile",
        "expression": "Gentle smile, contemplative, quiet — conveyed through a soft expression"
      },
      "pose": "Sitting on curb with knees drawn up, body curled inward, head tilted right, hands loosely clasped near shins, weight resting on feet — a compact, self-contained posture of solitude"

      "camera_height": "Standing eye-level (~160cm), subject on ground level",
      "framing": "Subject positioned in lower-right third; street and tree line create strong leading line vanishing left into deep background; three-layer depth: FG = fallen leaves carpet on pavement, MG = subject on curb boundary line, BG = row of trees, parked cars, apartment buildings receding into haze; generous headroom with tree canopy framing upper portion",
      "aspect_ratio": "4:5"
    },
    "lighting": {
      "type": "Natural ambient late-afternoon light, diffused through tree canopy, soft and warm",
      "direction": "Broad overhead-to-front, slightly from camera-left, no single hard source",
      "mood": "Gentle golden warmth wrapping the scene, low contrast ratio, subtle rim light on hair edges from ambient sky"
    },
    "color_palette": {
      "film_simulation": "Classic Negative (CN)",
      "style": "Fujifilm Classic Negative inspired color grading — nostalgic snapshot vibe, warm amber highlights from fallen leaves, cooler teal-green shadows in tree canopy and distant buildings, moderate contrast, subtle grain, skin tones preserved warm and natural",
      "tones": [
        "Dominant: golden amber / burnt sienna (fallen leaves carpet)",
        "Secondary: muted olive green (tree canopy) + cool blue-grey (distant buildings)",
        "Accent: platinum blonde hair as bright focal point against dark clothing"
      ],
      "grade_notes": [
        "highlight roll-off: soft, golden warmth retained",
        "shadow tint: cool teal-green, not crushed",
        "contrast curve: medium — enough separation without losing leaf detail",
        "grain: subtle film grain, visible on zoom"
      ]

    "environment": {
      "setting": "Autumn urban tree-lined boulevard, quiet side street in a Chinese city",
      "background": "Tall deciduous trees forming a canopy tunnel, parked cars along the road, apartment buildings in soft focus at the end of the street, a street lamp and speed limit sign mid-ground",
      "atmosphere": "Thick carpet of fallen leaves in golden yellow, brown, and occasional red scattered across the entire sidewalk and road surface — autumn at its peak, the air feels still and slightly cool, golden light filtering through sparse remaining canopy"
    },
    "mood": "Solitary autumn melancholy — poetic loneliness, the quiet beauty of being alone in a world that is gently decaying into gold, a stillness that feels chosen rather than imposed",
