A photorealistic portrait of a gorgeous young woman with a fit body, toned stomach, and narrow waist, standing in a graceful yet slightly lascivious pose. She has golden blonde hair flowing naturally, glowing blue eyes with intricate details, and a perfect, expressive face. Her small, natural breasts are accentuated by a delicate, underwater-themed dress that clings to her form, adorned with a bracelet, necklace, and anklet. She is barefoot, with a subtle emphasis on her curves (enhanced posterior:1.2). The setting is an ethereal underwater city of Atlantis, featuring submerged ruins, coral structures, and bioluminescent plants. Sun rays pierce through the water, creating dramatic lighting, dappled sunlight, and chiaroscuro effects. The background is slightly blurry with a bokeh effect (bokeh:1.2), showcasing a vibrant underwater ecosystem with fish, reefs, and anemones. The image is ultra-detailed, 8K resolution, with sharp focus, cinematic depth of field, and sparkling water effects. Emphasize realistic textures, intricate details (details:1.4), and a natural, dynamic lighting scheme with dramatic shadows.
