    "scene_description": "深秋与初春交界时分的无人旷野，枯黄与嫩绿交错的草原一直铺展到看不见尽头的天际线，天空是将暗未暗的靛蓝与残余橘粉交织的暮色，一条被季风吹得微微弯曲的泥土小径消失在远方浓重的雾气中，地平线上最后一缕光正在犹豫着要不要彻底熄灭",
    "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：深秋与初春交界时分的无人旷野，枯黄与嫩绿交错的草原一直铺展到看不见尽头的天际线，天空是将暗未暗的靛蓝与残余橘粉交织的暮色，一条被季风吹得微微弯曲的泥土小径消失在远方浓重的雾气中，地平线上最后一缕光正在犹豫着要不要彻底熄灭。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": "歌曲核心情绪是候鸟般反复迁徙的孤独与执着，62BPM慢速钢琴抒情曲带有强烈的回忆感和悲伤底色，复古空旷风景模板的荒野暮色意象最能传达这种'永远在路上、永远在回望'的漂泊感与眷恋。"
