Candid casting-style headshot portrait with GPT Image 2

A photorealistic portrait of a young woman in her mid-20s with medium-length straight dark brown hair falling loosely past her shoulders. She has light skin with subtle freckles across her nose and cheeks, warm brown eyes, and naturally full lips with a soft rosy tint. She is wearing a relaxed white linen button-up top with a wide neckline. Her accessories include a delicate gold chain necklace and a small round gold coin earring. She is posed in a three-quarter turn, glancing slightly upward toward the camera with a playful, closed-lip smirk, one cheek subtly puffed. The background is a clean, soft white wall with gentle natural light from the side. The overall mood is candid, warm, and natural. Shot in the style of a lifestyle or casting headshot - shallow depth of field, soft shadows, high detail on skin texture. No heavy retouching.
