    "subject": {
      "description": "一位时髦的年轻女子正自然俏皮地后仰跌入厚雪中。她抬头看向镜头，带着调皮的天然眨眼和灿烂笑容。",
      "action": "姿势动感且抓拍。在她落地/后仰瞬间，身体激起巨大雪浪。一只手急切伸向镜头（产生极端透视缩短），另一臂或肘部击中雪地，溅起白色雪尘向上飞扬。",
      "reference_slots": {
        "face_detail": "[用户人像图像：自然微笑+眨眼]",

    },
    "environment": {
      "setting": "阳光照耀的雪原，深蓝天空背景。视角让天空显得广阔无垠。",
      "atmosphere": "爆发且轻盈。空气中满是飞散的雪块与因撞击产生的细雪雾，营造'时间凝固'效果。",
      "sky": "澄澈无云的湛蓝天空。"

    },
    "lighting": {
      "type": "高调阳光",
      "quality": "晶莹透亮。阳光照射飞舞雪粒，化为闪亮焦外光斑。雪地充当补光，使皮肤显得透亮白皙。",

    "positive": "masterpiece, [用户人像], playful falling backwards into snow, candid shot, dynamic motion, winking one eye, natural bright smile, hand reaching towards camera, extreme foreshortening, touching the lens, massive snow splash, snow powder flying into air, exploding snow, trendy winter fashion, glossy puffer jacket, sunny winter day, clear blue sky, high key lighting, transparent skin, airy atmosphere, sparkling ice crystals, frozen motion, sharp focus on eye, 8k, Fujifilm color science.",
