手捧茶杯的安静动漫女学生

创作一张柔和、低调的动漫风格肖像，描绘一位处于安静自然状态的少女。她留着 {argument name="hair color" default="深棕色"} 中长发，发型略显凌乱，长刘海垂在额前，脸颊旁有几缕碎发，头顶右上方有一小撮向外翘起的头发。她的双眼半睁，略显疲惫，呈深棕色，表情中性且带着淡淡的沉思，脸颊上有浅浅的红晕。画面为半身像，她身体微向右转，视线看向左下方，双手将一个装有琥珀色茶水的透明玻璃杯捧在胸前。她身穿日本校服：白色衬衫，领口系着 {argument name="ribbon color" default="深红色"} 蝴蝶结，外搭一件超大号的 {argument name="cardigan color" default="暖米色"} 针织开衫，长袖遮住了部分手部；下部中央可见一颗深色纽扣。构图简洁亲密，人物略微偏左居中，背景为纯净的暖奶油色。采用细腻的手绘 2D 动漫插画风格，线条纤细且带有素描感，色彩为柔和的大地色系，搭配轻微的赛璐璐阴影和微妙的纸张纹理，对比度较低，无文字或装饰元素。整体氛围保持平静、忧郁且自然，避免使用高光、超写实主义或过于华丽的数字特效。

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.
