Акварельная аниме-иллюстрация в кафе

A stylish vertical anime fashion illustration in an expressive ink-and-watercolor painterly style, set at a small cafe table beside a window. A young woman named [Saiyu] sits in three-quarter view, wearing a wide black brimmed hat, short tousled [ash-brown hair], a black off-shoulder camisole dress with thin straps, a black choker, round black earrings, and glossy black nail polish. Her face is obscured by a single large centered opaque square censor block with a warm taupe-to-brown gradient, concealing most facial features while leaving part of one eye, hair, hat, ear, and shoulder visible. Her right hand reaches toward a black sealed envelope on the white tabletop; the envelope features exactly one round yellow lemon-slice wax seal. Beside it sits a tall clear glass of dark iced drink with one black straw, one yellow lemon wheel garnish on the rim, and a yellow circular emblem on the glass. A dramatic diagonal black window frame cuts across the left foreground, revealing blurred yellow flora outside. Loose brush texture, dry-brush shadows, sketchy ink borders, soft cream background, and a high-contrast limited palette of cream, black, charcoal, muted brown, and bright lemon-yellow accents. Small subtle signature reading "[SAIYU。]" in the bottom-right corner. Bittersweet, cinematic, and intimate atmosphere titled "[Letter Left Unsent]".
