Ethereal Serenity: Alexandra Daddario in a Lace-Clad Bathtub Portrait

"A photorealistic, highly detailed 8K cinematic portrait of Alexandra Daddario reclining comfortably on her back inside a smooth white bathtub. The tub is filled with clear water with a slight pale-blue tint. She has slightly wet and tousled black hair, and an extremely serene and peaceful expression as she looks directly at the camera. Her makeup is soft and natural, featuring light reddish-pink lips and nails painted in the same tone, complementing the realistic texture of her wet skin.

She is wearing a light green, long-sleeved, high-neck lace dress with intricate floral and geometric patterns, including a small bow tied at the neckline. The wet dress gently clings to her body while the fabric floats gracefully in the water. Her head is slightly tilted to the side near the edge of the bathtub. Her right hand rests softly on her stomach, while her left hand elegantly holds a single vibrant long-stemmed red rose close to her chest and face. Her right knee is slightly bent, visible just below the hem of the wet dress. Several pink carnation flowers float gently in the water around her.

The lighting is soft, bright, and diffused in a high-key style, creating an ethereal and dreamy glow. Delicate natural highlights reflect off her wet skin, the lace fabric, and the surface of the water, with minimal and soft shadows. The overall atmosphere is delicate, peaceful, dreamlike, and slightly melancholic, yet deeply beautiful. Captured from a high angle with a slightly tilted top-down perspective, framed as a medium to full-body portrait, with a soft yet sharp focus on her face and the red rose. --ar 9:16"
