写实风格日本烟花祭人像

创作一张高度写实的竖版祭典人像，主角为 {argument name="character description" default="一位 20 出头的美丽日本女性"}，背景设定在日本夏夜的烟花祭。画面采用腰部以上的半身构图，她以四分之三侧身站立，微微转头，回眸直视镜头，带着温暖自然的微笑。她留着深棕黑色的柔顺秀发，梳成松散的低发髻，留有轻盈的刘海和修饰脸型的发丝，发间装饰着两朵菊花造型的发饰，分别为奶油色和粉色。她身穿一件淡奶油色浴衣，上面印有精致的紫色和薰衣草色花卉图案，背后系着巨大的米色腰带结，一只手提着一个小巧的碎花束口袋。背景是热闹的祭典街道，左右两侧各有两排灯火通明的摊位，挂着红白相间的灯笼，身着浴衣的游客在人群中穿行，远处可见中层城市建筑。在她的上方，深蓝色的暮色天空中绽放着多朵巨大的粉色、紫色、白色和金色烟花，画面顶部至少有三处醒目的烟花爆炸效果。利用温暖的灯笼光照亮她的面部和浴衣，营造柔和的背景虚化效果，呈现真实的皮肤纹理、自然的妆容、电影级的景深，具有手持街拍的质感，细节丰富，采用 photorealistic gpt-image-2 风格。强调 {argument name="mood" default="浪漫、喜庆、生动且栩栩如生"} 的氛围。使用 4:5 竖版构图，平视视角，主体略微偏左，烟花在她头后形成明亮的光环，无文字，无水印，无扭曲的手部，无多余的手指。

Create a highly realistic vertical portrait photo of {argument name="character name" default="a beautiful Japanese woman in her 20s"} at a summer evening fireworks festival in Japan. She is shown from the waist up in a three-quarter back-facing pose, turning her head over her shoulder to smile warmly at the camera, with natural expressive eyes, soft skin texture, and an approachable candid expression. She wears a pale cream-pink yukata with purple and lavender floral patterns, a large beige obi bow tied at the back, and small pink and cream chrysanthemum hair ornaments tucked into a low updo with loose bangs and face-framing strands. Her right hand holds a small floral drawstring kinchaku pouch with thin red cords. The setting is a crowded Japanese matsuri street at dusk, lined with glowing food stalls and red-and-white festival banners, warm paper lanterns, and many festivalgoers in colorful yukata walking away in the background. Above her, the blue twilight sky is filled with large bright fireworks bursts in pink, purple, white, and gold, slightly blurred by depth of field but still dramatic and luminous. Use a close 3/4 portrait composition, subject centered slightly right, shallow depth of field, realistic lens perspective, warm lantern light on her face and yukata, cool blue ambient evening light in the sky, cinematic color grading, crisp detail on the woman and soft bokeh background. Emphasize photorealism, natural human proportions, realistic fabric folds, authentic Japanese summer festival atmosphere, and a joyful romantic mood. Avoid extra text, logos, watermarks, distorted hands, plastic skin, over-smoothed face, or anime styling.
