Warm Smile Portrait

Ultra-realistic portrait of a young woman with a warm, friendly smile, looking directly at the camera. She has long, straight dark hair with a smooth natural shine, light green eyes, and soft, clear skin with natural makeup. She is wearing round, thin metal-framed glasses and a black fitted top layered under a brown plaid pinafore dress. She is holding a smartphone with both hands at chest level.
The setting is a cozy indoor environment with a softly blurred bookshelf in the background, creating a warm and calm atmosphere. Lighting is soft and natural, coming from the front, highlighting facial features with gentle shadows. Cinematic depth of field, sharp focus on the subject, highly detailed skin texture, professional photography, 85mm lens, f/1.8, ultra HD, realistic color grading.
