A photorealistic, hyper-detailed portrait of a young woman, in the style of a clean digital sketch. The image should be in black and white with a pure white background. The subject has long, flowing blonde hair with soft waves. Her expression is serene and captivating, with a slight, gentle smile and direct eye contact. Use soft, directional lighting to create delicate shadows and highlights on her face and neck. Emphasize intricate details in the hair, eyes, and lips, maintaining a smooth, elegant, and clean aesthetic.
