GPT Image 2.5 on ChatGPT Prompt; Use the uploaded reference photo as the exact identity reference. Preserve the girl’s facial features, face shape, hairstyle, and natural appearance. Create a photorealistic nighttime iPhone 17 Pro front-camera selfie, with no phone visible. The girl is sitting comfortably, leaning slightly to one side, with her chin gently lowered and her eyes looking directly past the camera with a calm, mysterious expression. One hand rests behind her head, loosely lifting her long, slightly messy hair. A few strands naturally frame her cheeks. Her lips are softly closed with a subtle pout. Accessories: a single black clover bracelet on her wrist, small understated earrings, and short milky-white square nails. Makeup features delicate winged eyeliner, long fluttery lashes, softly defined laminated brows, and glossy nude-pink lips. She wears a simple black off-shoulder top. The background is almost completely dark. Soft amber light falls diagonally across one side of her face, creating deep natural shadows and subtle highlights in her hair. Close-up framing, slightly off-center composition, authentic smartphone selfie perspective, realistic pores and skin texture, subtle sensor grain, low exposure, muted colors, and imperfect candid details. The result must look like a genuine late-night personal selfie, intimate and effortlessly beautiful, not a professional photoshoot. No HDR, beauty filters, skin smoothing, artificial shine, excessive retouching, extra jewelry, or changes to her identity. Vertical 9:16 composition.
