Crowd-mosaic portrait made of thousands of tiny people

Create a high-contrast photorealistic crowd-mosaic portrait of a woman with fair skin, green eyes, and long flowing auburn-red hair, on a pure white background. She is centered, looking directly at the viewer with a subtle confident smile, one hand resting gently against her lips in a "shh" gesture. The entire image is composed of thousands of tiny human figures, with every color, shadow, and detail formed solely by densely packed people. Her fair skin is created from figures in beige, peach, cream, and tan clothing; her eyes and facial features are defined by darker-clothed figures; and her hair is formed from people wearing shades of red, burgundy, copper, and brown. She wears a dark top made from clusters of black and gray-clothed figures. Around the edges of the portrait, individual people break away and scatter across the white ground, becoming more sparse with distance and casting realistic shadows. From afar, the artwork appears as a realistic portrait; up close, it reveals thousands of individual people. Ultra-detailed optical-illusion crowd art, cinematic lighting, crisp focus, museum-quality realism, aerial crowd-art effect, minimalist composition, extremely sharp detail, 8K resolution.
