Lavender Sweater Floor Portrait

Create a square artistic floor-seated portrait of a {argument name="character age and gender" default="20-year-old girl"} sitting on a pale wooden studio floor in soft natural light. She wears a {argument name="sweater color and style" default="soft lavender chunky knitted sweater"}, loose cream wide-leg pants, and pastel gray low-top sneakers with white soles. Her waist-length wavy milky brown hair falls over her shoulders and is styled half braided. Pose her seated casually with one knee raised, arms wrapped gently around the knee, one leg tucked under, relaxed posture, and a gentle smiling mood; keep the face area intentionally covered by a large opaque warm gray rectangular privacy block centered over the head and upper torso. The background is a textured off-white plaster wall covered with dramatic oversized black-and-white abstract portrait collage art, including a large grayscale side-profile face, visible ear, dark brush strokes, torn-paper textures, and rough painterly patches. Use a calm editorial fashion photography style, muted pastel palette, realistic fabric texture, soft shadows, shallow depth of field, clean composition, no text, no watermark.
