Boceto de una mujer relajada en el sofá

A soft, muted anime-style interior illustration of a young woman lounging sideways on a sofa in a relaxed, unposed way. She has {argument name="hair color" default="dark brown"} long slightly messy hair with loose strands falling over her shoulders, and she is wearing an oversized off-shoulder knit sweater in charcoal gray that slips down to reveal one shoulder, plus loose light beige sweatpants and soft socks. Her pose is casual and limp, with her body curled across the couch, one elbow propped into a large cushion, her hand supporting her cheek, and her legs folded to the side. Her visible expression should feel tired, quiet, introspective, and emotionally drained but comfortable. The scene is framed as a medium full-body shot from the front at sofa height. The room is calm and minimal, with 1 sofa, 3 large cushions, 1 round wooden coffee table in the foreground, 1 ceramic mug on the table with a simple cat doodle and the handwritten text "ねこ", 1 smartphone lying flat on the table, 1 notebook or paperback book with small Japanese handwriting on the cover, 1 small paper note taped to the wall reading "なんとかなるよ", and 1 leafy plant branch entering from the upper right side. Use a desaturated warm gray and beige palette, delicate pencil-like linework, light watercolor wash shading, subtle texture like sketch paper, and a wistful slice-of-life mood. Keep the composition airy, intimate, and understated, like a quiet illustration from a lifestyle art book.
