Create a highly detailed 8K vertical portrait in 9:16 aspect ratio of a young beautiful woman based on the uploaded photo reference, preserving all facial features exactly — do not alter her eyes, nose, lips, or any aspect of her face. Pose/Expression: She is lying casually on a white furry sofa, leaning diagonally, holding an iPhone in her hand with a confident, playful gaze, looking straight at the camera. Hair: long, thick dark brown hair, styled in loose waves, falling freely over her shoulder. Outfit: Oversized short red jersey with a large black "11", showing her waist, paired with loose, relaxed blue jeans sitting low on her hips, revealing a white boxer belt underneath. Accessories: Layered gold necklace, gold bracelets, diamond ring subtly sparkling in the light. Long pointed glossy nails. Makeup: Maintain facial features exactly. Beige eyeshadow with slight shimmer, eyeliner, strong contour, rosy cheek tone, perfect glowing skin, full plump lips with dark brown lipliner, long natural black eyelashes, and cared brows with lifting effect. Lighting/Style: Sandy 90s-style aesthetic with subtle camera flash highlighting her glowing skin and outfit. Background: Modern, comfortable interior, minimal and slightly blurred to emphasize the subject, soft and cozy atmosphere. Camera & Composition: Full 9:16 vertical framing, cinematic crop, professional camera simulation, ultra-sharp 8K detail, realistic textures on hair, skin, outfit, and accessories, subtle cinematic bokeh. Atmosphere/Mood: Playful, stylish, casual streetwear Y2K vibe, dreamy and confident, emphasizing vertical composition for social media or editorial formats.
