Soft Pastel Anime Girl Puzzled Portrait

A soft, minimalist anime-style half-length portrait depicts a lovely young woman against a pure light gray background. Painted in a clean pastel style, the lines are delicate like a sketch, and the colors are flat and soft. She has long, flowing, light blonde hair with soft layers, partially obscured by long bangs. She has large, round, light blue eyes, fair skin, and a slightly parted mouth that reveals a hint of confusion. She wears a loose-fitting long-sleeved top with a wide, comfortable neckline. Her pose is slightly turned towards the viewer, one hand raised, index finger lightly touching the side of her head, as if puzzled. A floating blue question mark is placed in the upper left corner of her head. Her expression should be innocent, absent-minded, and endearing. The composition should be centered, open, and simple, without extra objects, complex backgrounds, or strong shadows.
