A sunlit vertical portrait of a young woman

A sunlit vertical portrait of a young woman seated on a sandy beach, three-quarter profile facing the camera with a gentle, natural smile and warm eye contact; she wears a flowing pastel sky-blue dress with loose sleeves and a gathered waist, hair long, voluminous and wavy chestnut-brown with soft highlights and a slight breeze moving strands; delicate floral chandelier earrings catch the light. Background of gently blurred ocean horizon and soft waves under a pale blue sky. Cinematic soft natural light with warm highlights and subtle rim/backlight, shallow depth of field (classic 85mm portrait feel, wide aperture) for creamy bokeh. Soft filmic color grading in pastel tones, natural skin retouching preserving texture and pores, visible catchlights in the eyes, realistic high-resolution detail, sharp focus on the face, soft fabric texture, relaxed elegant mood, balanced composition with negative space and serene coastal atmosphere. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
