(ultra photorealistic portrait of a stunning 18-year-old Scandinavian woman, kneeling gracefully in perfectly calm shallow water at golden hour, mirror-like reflections rippling gently around her legs, vivid warm sunset filling the sky with glowing oranges, pinks, and purples, the horizon softly blurred, sunlight catching highlights in her hair and on her skin), (long straight platinum-blonde hair — not white, natural golden undertones shimmering in the light, silky smooth strands flowing over her shoulders), (vibrant bright blue eyes locked onto the viewer with a seductive, confident gaze, full glossy lips biting gently on her lower lip), (flawless fair skin with faint freckles across her cheeks and nose, natural blush on her cheeks), (large natural round breasts, perfectly shaped, firm and lifted, standing proud without sag), (wearing a low-cut, thin, tight-fitting top clinging to every contour of her chest, neckline plunging deep between her breasts, her hands grasping the edges of the neckline and pulling it wider to expose more cleavage, fingertips pressing lightly into her skin), (subtle forward arch of her upper body enhancing bust line, collarbones defined), (soft warm sunlight casting golden highlights and long shadows, high dynamic range capturing detail in both light and shadow, cinematic composition, 8k resolution, extreme detail in skin texture, hair strands, fabric folds, and water reflections), (perfect skin, hyperrealistic, ultra sharp, professional studio-meets-nature lighting)
