Draw a 16-year-old girl with a slim and slender figure. Her hair is blonde and very straight, falling softly over her shoulders and framing her face. She has large, expressive light brown eyes that show innocence. Her lips are pink and very thin, adding a touch of delicacy to her expression. Her complexion is clear and luminous, with a natural light blush on her cheeks. Her nose is slightly upturned, giving her a youthful and charming appearance. A black headband covers her entire forehead down to her eyebrows, fitting snugly but elegantly, and is discreetly hidden among her hair on the sides.
