忧郁动漫少女手持茶杯

创作一张简约的正方形动漫风格插画，画面中一位忧郁的少女正双手捧着一个透明玻璃茶杯。角色拥有 {argument name="hair color" default="深炭黑色"} 的中长直发，刘海柔软凌乱，左侧有几缕发丝向外卷曲，长鬓角，带有淡淡的灰色高光，整体呈现出自然且略显随意的质感。她皮肤白皙，一双疲惫的大眼睛看向左下方，眉毛纤细，鼻梁小巧，嘴唇微抿向下，流露出安静内省的情绪。她身穿一件宽松的 {argument name="cardigan color" default="暖米色"} 开衫，袖子宽大，内搭一件简约的 {argument name="shirt color" default="白色"} 圆领衫。她的双手靠近胸前，手指环绕着一个透明的圆柱形玻璃杯，杯中盛着半杯 {argument name="drink" default="红茶"}。采用干净的现代日本动漫美学，线条柔和纤细，色彩柔和，带有轻微的赛璐珞阴影，纹理极简，画面无文字。构图为胸部以上的居中四分之三侧面视角，头部微微低垂，双肩放松。背景为纯净的浅灰白色，无任何物体或景物，以突出安静的情绪肖像。

Create a simple square anime-style illustration of a melancholic teenage girl holding a clear glass of tea with both hands. The character has {argument name="hair color" default="dark charcoal black"} medium-length straight hair with soft messy bangs, a few loose strands curling outward on the left, long side locks, subtle gray highlights, and a natural slightly unkempt shape. She has pale skin, large tired dark eyes looking down and to the left, thin eyebrows, a tiny nose, and a small neutral downturned mouth, giving a quiet introspective mood. She wears a loose {argument name="cardigan color" default="warm beige"} cardigan with oversized sleeves over a plain {argument name="shirt color" default="white"} crew-neck shirt. Her hands are close to her chest, fingers wrapped around one transparent cylindrical glass filled halfway with {argument name="drink" default="brown tea"}. Use a clean modern Japanese anime aesthetic with soft thin line art, muted colors, gentle cel shading, minimal texture, and no text. Frame her from the chest up in a centered three-quarter view, head tilted slightly downward, shoulders relaxed. The background is a plain very light gray-white with no objects or scenery, emphasizing the quiet emotional portrait.
