ภาพเหมือนของสาวอนิเมะผมบลอนด์ที่ดูสับสน

A soft, minimalist anime portrait of a cute young woman from the waist up 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 conveying mild confusion. She is wearing an oversized loose {argument name="clothing color" default="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 as if puzzled. Place exactly 1 floating blue question mark near the upper left side of her head. The expression should feel innocent, absentminded, and endearing. Keep the composition centered, airy, and uncluttered, with no extra objects, no detailed background, and no strong shadows.
