Detailed Melancholic Anime Girl Holding Tea Composition

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.
