Masterful Yellow Mixed Media Portrait Poster Study

Create a modern mixed media editorial poster portrait of a {argument name="subject" default="young South Asian woman"} from the waist up, centered and facing forward, with long voluminous wavy dark brown hair over both shoulders, wearing a bright {argument name="shirt color" default="mustard yellow"} short sleeve pocket T shirt. Obscure the entire face with a centered solid rectangular privacy block in medium warm brown, covering from forehead to chin while leaving hair, neck, and clothing visible. Place the portrait inside a large mustard yellow circular cutout with a thin white rim. Behind it, use a warm beige paper texture background with layered graphic collage elements: one tilted white rectangular frame behind the circle, broad rough yellow paint brush strokes sweeping diagonally from the upper right and lower left, a black botanical branch with exactly 14 visible dark leaves along the left side, a yellow dotted halftone grid in the upper left, a black dotted halftone field in the lower right, a faint yellow square grid on the right, small black circular line art near the lower right edge of the circle, and subtle gray ink splatter textures. Keep the composition vertical, high contrast, stylish, clean, and poster like, with no readable text and no watermark.
