Create a realistic Gen Z-inspired selfie collage portrait in a vertical 9:16 frame. The layout is [Layout] featuring one young adult woman. She has long dark wavy hair, dewy luminous skin, rosy cheeks, glossy peach-toned lips, and natural minimal makeup. Her clothing is [Clothing], with [Accessory], dark nail polish, and delicate manicured nails.
Show three expressive selfie moments in the collage: resting her chin on her hand, playfully winking with her tongue out, and smiling warmly. Use front-facing phone-flash photography, a plain light-gray background, dramatic high-contrast flash shadows, shallow depth of field, crisp facial detail, realistic skin texture, and high-resolution photorealism. Keep the mood casual, playful, and profile-photo friendly, with a Y2K social-media aesthetic and a cinematic 35mm film texture.
Constraints: the subject must be an adult. Do not imitate a real person, celebrity, influencer, or private individual. Do not include Instagram branding, Nirvana branding, real band names, readable logos, trademark symbols, UI chrome, watermark, private information, or extra people. Any lettering on clothing must be abstract and unreadable.
