Задумчивая аниме-школьница с чаем

A delicate, hand-drawn 2D anime illustration of a teenage schoolgirl in a quiet candid moment, framed from the chest up. She is turned slightly to the right while looking down-left, holding a clear glass tumbler of amber tea close to her chest with both hands. She has [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 on the upper right side. Her deep brown eyes are half-lidded and tired-looking, with a neutral, mildly pensive expression and faint blush on her cheeks. She wears a Japanese school uniform with a white collared shirt, a [dark red] bow ribbon at the neck, and an oversized [warm beige] knit cardigan with long sleeves covering part of her hands, with one dark button visible near the lower center. Centered slightly to the left on a plain warm cream background. Thin sketchy linework, muted earthy colors, soft cel shading, subtle paper-like grain texture, and low contrast. Calm, melancholic, natural mood, with no glossy highlights, hyperrealism, or decorative text.
