柔和蓝色动漫少女肖像

A soft anime-style bust portrait of a cute young woman centered on a plain warm off-white background, drawn with clean delicate line art and flat pastel coloring. She has very long straight {argument name="hair color" default="pale sky blue"} hair with wispy strands, full bangs parted slightly near the center, and large matching blue eyes with glossy highlights. Her expression is shy and puzzled, with slightly raised inner eyebrows, faint pink blush on her cheeks, and a small open mouth. She is looking directly at the viewer while lightly touching her lower lip with one index finger in a thoughtful, hesitant pose. She wears an oversized loose {argument name="top color" default="light blue"} sweatshirt with long sleeves that partly cover her hand. Frame the image from the chest up, with the head slightly tilted, giving a gentle, innocent, dreamy feeling. Use a minimalist composition, no accessories, no extra objects, no scenery, and no text. Emphasize a monochrome blue palette, airy simplicity, subtle sketch-like outlines, and a clean Japanese illustration aesthetic suitable for a soft personal avatar.
