角色设定 GPT Image 2 提示词：Flash Night Beach Portrait

A candid photorealistic night beach portrait of a young woman standing on wet sand near the shoreline, framed from mid-thigh up, facing the camera with a relaxed posture and one arm hanging naturally at her side. She has long straight dark brown hair parted near the center, smooth light-to-medium skin, and wears a fitted strapless bodycon dress with a soft vintage floral print in muted cream, pale yellow, sage green, and dusty blue. Add a delicate gold necklace with a small round pendant and subtle rings on her fingers. The scene is lit with direct on-camera flash, creating sharp realistic highlights on the skin, a crisp subject against a very dark background, and a visible band of foamy ocean waves behind her. The beach and sea should look natural and dim, with the horizon fading into black night sky. Smartphone snapshot aesthetic, realistic skin texture, slight flash harshness, casual social-photo composition, shallow ambient detail, centered subject, authentic nightlife beach vibe.
