A split-panel or side-by-side portrait of a {argument name="subject" default="woman with wavy, light brown hair"} styled half-up, wearing a {argument name="clothing" default="cozy black knit sweater"} and a layered silver and gold chain necklace. In the first view, she is captured in a candid three-quarter profile, resting her chin on her hand with a joyful, beaming smile, looking slightly off-camera. In the second view, she looks directly at the camera with a playful, mischievous expression, crinkling her nose and gently biting her lower lip. Both shots share a {argument name="background" default="warm, natural indoor setting"} with soft lighting, a blurred bookshelf, and a textured brick wall in the background, maintaining perfect facial and stylistic consistency across both expressions.
