Quiet Anime Schoolgirl Holding Tea

Create a soft, understated anime-style portrait of a teenage schoolgirl in a quiet candid moment. She has hair color medium-length slightly messy hair with long bangs falling over her forehead, a few loose strands around her face, and one small outward flick of hair near the upper right side of her head. Her eyes are half-lidded and tired-looking, colored deep brown, with a neutral, mildly pensive expression and faint blush marks on her cheeks. She is shown from the chest up, turned slightly to the viewer’s right while looking down-left, holding a clear glass tumbler of amber tea close to her chest with both hands. She wears a Japanese school uniform: a white collared shirt, a ribbon color bow ribbon at the neck, and an oversized cardigan color knit cardigan with long sleeves covering part of her hands; include one visible dark button near the lower center. The composition is simple and intimate, with the character centered slightly left on a plain warm cream background. Use a delicate hand-drawn 2D anime illustration style with thin sketchy linework, muted earthy colors, soft cel shading, subtle paper-like grain texture, low contrast, and no text or decorative elements. Keep the mood calm, melancholic, and natural, avoiding glossy highlights, hyperrealism, or overly polished digital effects.
