    "scene_description": "深冬凌晨将明未明的时刻，一片被浓霜覆盖的空旷原野向远方无限延伸。地平线处透出一缕极淡的靛蓝色微光，像是黎明犹豫着要不要到来。一条窄窄的泥径消失在低垂的薄雾中，两侧银白色的枯草在寒风中微微颤动。天空从深紫缓缓渐变为灰蓝，几颗将要隐没的星子散落其间，整个画面弥漫着一种温柔却永远无法触及的遥远感。",
    "cover_prompt": "生成一张拍立得（Polaroid）风格的无字版音乐专辑封面。画面描绘的是：深冬凌晨将明未明的时刻，一片被浓霜覆盖的空旷原野向远方无限延伸。地平线处透出一缕极淡的靛蓝色微光，像是黎明犹豫着要不要到来。一条窄窄的泥径消失在低垂的薄雾中，两侧银白色的枯草在寒风中微微颤动。天空从深紫缓缓渐变为灰蓝，几颗将要隐没的星子散落其间，整个画面弥漫着一种温柔却永远无法触及的遥远感。整体画面必须呈现真实拍立得相片的质感：略微过曝的柔和光线、轻微偏色的复古色调、自然的暗角和柔焦边缘、细腻的胶片颗粒感。色彩是褪色、怀旧的暖色调，仿佛一张被遗忘在抽屉里多年的即时成像照片。强烈要求：画面必须是纯粹的风景，绝对不要出现任何人物、人影、手或脸！绝对不要生成任何文字、字母、歌名或水印！保持空灵、孤独和冥想的氛围。",
    "selection_reason": "歌曲核心情绪是深夜思念远去之人的孤独与不舍，BPM 68的慢速钢琴抒情曲带有强烈的回忆感和cinematic氛围，适合用空旷风景来隐喻那种'温柔却触不到'的遥远感，复古拍立得质感与怀旧思念的基调高度吻合。"
