Joyful Laughing Portrait

Create a photorealistic close-up portrait of a young {argument name="subject description" default="Japanese woman in her 20s"} laughing joyfully, facing the camera directly. She has {argument name="hair color and style" default="auburn-red medium-length hair with soft waves and straight bangs"}, fair natural skin, subtle makeup, visible eyelashes, and a huge open-mouth smile showing bright white teeth, with her eyes nearly closed from laughter and gentle smile lines around the cheeks. She wears a {argument name="clothing" default="black ribbed turtleneck sweater"}. Frame her from the upper chest upward, centered but slightly leaning forward, with hair falling over both shoulders. Use a clean {argument name="background" default="plain light gray studio background"}, soft even daylight-style illumination, realistic skin texture, shallow depth of field, crisp focus on the face, natural colors, minimal shadows, no jewelry, no text, no watermark, and a candid editorial beauty photography feeling.
