Human and Mini-Me Studio Portrait

Create an ultra-realistic full-body studio portrait showing exactly two versions of the same {argument name="character identity" default="adult Black man"} standing side by side against a seamless warm beige photography backdrop. On the left is the full-size realistic human version: tall, stylish, confident, short neatly trimmed black hair, smooth clean-shaven face, wearing black angular sunglasses, looking downward toward the smaller version with a calm cool expression. On the right is one miniature stylized 3D cartoon version of the same man, about one third of the human's height, with an oversized head, large expressive eyes, rounded youthful facial features, short black hair, and a charming confident pose, looking up at the human version. Both figures wear the same outfit: a deep {argument name="shirt color" default="navy blue"} long-sleeve button-down shirt with sleeves rolled to the forearms, {argument name="trouser color" default="camel brown"} tailored dress pants, a brown leather belt with metal buckle, brown polished dress shoes, and a gold wristwatch. The human stands with both hands in his pockets, feet slightly apart; the miniature cartoon also stands with hands in pockets, mirroring the pose. Use professional studio lighting with soft shadows on the floor, warm tan gradient background, high-fashion editorial composition, crisp realistic fabric textures on the human, glossy high-quality Pixar-like 3D rendering for the miniature, harmonious scale contrast, vertical 2:3 framing, full bodies visible from head to shoes, no text, no logos, no extra people, no props.
