Create a stunning, high-resolution artwork inspired by the classic Disney character Ariel from The Little Mermaid, depicted as a vibrant 17-year-old. Capture her in a graceful, alluring pose, fully underwater with a mesmerizing sea background. The image should showcase exquisite detail and clarity, reminiscent of a 16k, UHD, HDR masterpiece. Ensure the focus is on the natural beauty and wonder of the character and setting, avoiding any distortions or low-quality elements such as mutations, clones, or extra body parts. Keep it clean and free from any distractions like watermarks, logos, or unnecessary text, and aim for a seamless, cohesive portrayal that maintains the enchantment of the scene.
