Joven con bikini magenta en azotea urbana soleada

A high-fashion editorial portrait shot with an 85mm lens, 9:16 aspect ratio. A young woman with wavy, sun-kissed brunette hair and natural makeup leans back against a textured concrete balcony pillar on a rooftop. She wears a vibrant magenta two-piece string bikini featuring a small floral accent at the center of the halter top and side-tie bottoms. Golden hour natural sunlight casts warm, soft highlights on her skin and subtle shadows across her face and torso. In the background, a blurred urban city skyline under an open blue sky with soft white clouds, shallow depth of field, high contrast, film grain texture, photorealistic 8k.
