熊耳罩三姐妹的列车合影

创作一张温暖可爱的通勤列车生活方式照片：三位明确成年的日本三姐妹外貌相同、亲密并排坐在有图案的列车座椅上，朝镜头露出柔和笑容。她们都有圆润柔和的脸型、明亮有神的眼睛、黑色直发与齐薄刘海；三人穿搭协调，但各自动作不同：一人以手托下巴，一人在脸颊旁比出剪刀手，另一人双手捧着纸咖啡杯。她们戴毛茸茸的棕色泰迪熊耳罩，穿奶油色露肩罗纹针织衫、黑色百褶裙、细珍珠项链和白色蕾丝边及膝袜，造型清新可爱、得体不挑逗。手机挂有白色毛球挂件，咖啡杯使用简洁可爱的熊形杯套和毛球装饰，不出现可读品牌文字。背景为日本通勤列车内饰，木质墙板、织物座椅、大窗户与柔和顶灯；自然窗光和暖色室内光混合，人物清晰、车厢背景轻微虚化。采用平视中景构图，奶油色、柔棕、黑色与温润木色为主，营造舒适、亲密、俏皮的瞬间。不要文字、标志或水印。参考图用于三位成年姐妹之间保持相同的通用面部外观，不对应特定真实人物。

【English Prompt】
Create a warm, cute commuter-train lifestyle photograph of three clearly adult Japanese triplet sisters with matching appearance, sitting close together on patterned train seats and smiling softly toward the camera. Give all three softly rounded faces, bright expressive eyes, straight black hair, and light see-through bangs. Coordinate their outfits but give each a distinct gesture: one rests her chin on her hand, one makes a peace sign beside her cheek, and one holds a paper coffee cup with both hands. They wear fuzzy brown teddy-bear earmuffs, cream off-the-shoulder ribbed knit sweaters, black pleated skirts, delicate pearl necklaces, and white lace-trim knee socks—cute, composed, and non-suggestive styling. Their phones have white pom-pom charms; the cups have simple cute bear sleeves and pom-pom accents without readable branding. Set the scene inside a Japanese commuter train with wood-paneled walls, patterned fabric seats, large windows, and warm overhead lights. Mix soft daylight from the windows with a cozy indoor glow. Use an eye-level medium shot, keeping the sisters clear and the carriage gently softened behind them. Favor cream, soft brown, black, and muted wood tones for an intimate, playful everyday moment. No text, logos, or watermark. Use the reference to keep the three adult sisters' generic facial appearance consistent, not to depict any specific real people.
