Elegant woman in blue gown by the twilight ocean

Prompt: An ultra-realistic full-body shot of a tall, graceful woman standing near the serene tide of a deep blue ocean during the twilight blue hour. The image features a heavy monochromatic blue color palette—mysterious navy sky, dark cyan ocean, and shimmering sapphire tides. She is dressed in an elegant ocean-blue high-slit satin gown, reflecting the cool blue ambient lighting. Her posture is effortless and sophisticated. The camera pulls back to reveal the full figure, placing her gracefully off-center with ample background space of rolling water and misty horizon. Highly photorealistic, 2K resolution, realistic water physics, atmospheric lighting. --ar 4:5
