Confused Blonde Pastel Anime Girl

A soft, minimalist anime portrait from the waist up of a cute young woman against a plain light gray background. Drawn in a clean pastel style with very thin sketch-like line art and flat, gentle colors. She has long, flowing pale blonde hair with soft layers and long front bangs partially covering her forehead, large round light-blue eyes, fair skin, and a small, slightly open mouth showing mild confusion. She wears an oversized loose [light pastel blue] long-sleeve top with a wide relaxed neckline. Her pose is slightly angled toward the viewer, with one hand raised and one index finger touching the side of her head puzzledly. Exactly one floating blue question mark appears near the upper left side of her head. The mood is innocent, absentminded, and endearing. Centered, uncluttered, airy composition with no extra objects, no detailed background, and no strong shadows.
