Clean Vector Portrait of Woman with Glasses

Create a minimalist clean flat vector portrait of {argument name="character description" default="a young woman"} shown from the chest up, centered on a square canvas. She has {argument name="hair color and style" default="long straight dark brown-black hair with soft wispy bangs and loose shoulder-length layers"}, warm light-medium skin, delicate facial features, almond-shaped open eyes looking calmly forward, subtle eyeliner, natural lips, and a soft closed-mouth smile. She wears {argument name="glasses style" default="thin black-rimmed round glasses"} and {argument name="outfit" default="an oversized plain black crewneck sweatshirt"}. Pose her with one hand gently resting against her cheek near the glasses frame, elbow implied below the crop, relaxed and thoughtful. Use a modern digital vector illustration style with smooth simplified shapes, crisp dark outlines, painterly cel-shaded shadows, warm orange highlights on skin and hair, detailed but stylized hair strands, and no visible texture or text. Set the portrait against a solid {argument name="background color" default="dark warm brown"} background, with soft frontal lighting, high contrast between the black clothing and warm face, clean edges, no accessories besides the glasses, no watermark, no border.
