Product Marketing - Sunny Beach Straw Hat Portrait

Create a photorealistic vertical beach portrait of a young {argument name="subject description" default="East Asian woman in her early twenties"} standing by a vivid turquoise ocean under a bright blue summer sky. She is shown from the waist up in a three-quarter back pose, turning her head toward the camera with a soft confident half-smile and relaxed eyes. She wears a wide-brim natural straw sunhat with open woven texture and a dark navy rim; one hand lightly touches the brim near her cheek. Her {argument name="hair style" default="black hair loosely tied in a low messy bun with wispy strands around her face"} is slightly windblown. The hat casts delicate dotted lattice shadows across her face, neck, shoulder, and upper back. She wears a {argument name="outfit" default="white off-shoulder eyelet lace summer blouse with floral cutout embroidery"}, with two thin silver swimsuit straps visible on one shoulder. Background: shallow turquoise seawater in the lower half, a softly blurred distant island on the left horizon, and exactly 3 small soft white cloud areas in the blue sky. Use bright midday sunlight, warm natural skin tones, crisp focus on the face and hat texture, shallow depth of field, realistic lens compression, airy tropical vacation mood, high-resolution editorial photography, vertical 9:16 composition.
