Portrait anime illustration

Create an anime-style close-up portrait featuring , facing the camera, against a pure white background. She has long straight hair, , blunt bangs, glossy sketch-like highlights, and hair falling past her shoulders; both ears are faintly visible through the strands. The image shows only the upper body, wearing a crisp shirt with a dark tie or inner placket, and a dark brown choker around her neck. Thin glasses frames are faintly visible on the left and right sides of her face. Use a refined Japanese manga/anime illustration style, clear linework, dense hatching in the hair, soft cel shading, natural skin tones, and a vertical portrait composition. Place a large opaque square mosaic at the center of the entire face, covering from the forehead down to just above the chin, in a soft brown-to-taupe vertical gradient, hiding the eyes, nose, mouth, and most of the glasses, while keeping the hair, ears, neck, collar, and shoulders visible. No text, no watermark, no extra objects.
