Portrait anime illustration cool tone

Create an exquisite anime-style vertical portrait showing a close-up three-quarter view of a high school girl, framed from above the chest to above the head. She has slightly messy dark navy-black long hair, with fine strands brushing her cheeks and shoulders, soft pink rim light on the left, and cool blue shadow on the right. Her face is deliberately covered by a large opaque soft magenta square block centered on her face, hiding all facial features. She wears a Japanese school uniform: dark blazer, white shirt collar, red ribbon bow, a light gray hoodie layered under the blazer, with the hood visible behind her neck; at the bottom right, a dark blue school bag is visible, with clear shoulder straps and a rounded body. One hand grips the strap or lapel at her chest. Use delicate line art, painterly cel shading, highly detailed hair strands, soft backlight, light white background, gentle spring atmosphere, and a clean modern anime illustration style. Keep the composition intimate and vertical, with no text, watermarks, or extra characters in the image.
