Cozy Sleepy Girl Portrait Before Sahur

Create an ultra-realistic 8K portrait in 9:16 resolution of a woman sitting cross-legged on the floor, leaning against a plain white wall. She looks sleepy and slightly drowsy, as if fighting off sleep before sahur. One hand is raised gently near her eye, as though rubbing it or trying to stay awake. She is wearing a loose grey sweater and matching loose grey pants. The outfit looks soft and comfortable, suitable for resting at home. Use soft, natural lighting with subtle shadows. Minimalist setting, clean white background, high detail, cinematic atmosphere, sharp focus, realistic skin texture, professional photography style, calm and cozy mood.
