Quiet Anime Schoolgirl Holding Tea Visuals

Create a soft, understated anime style portrait of a teenage schoolgirl in a quiet candid moment. She has {argument name="hair color" default="dark brown"} 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 {argument name="ribbon color" default="dark red"} bow ribbon at the neck, and an oversized {argument name="cardigan color" default="warm beige"} 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.
