Create an exquisite, high-resolution visual inspired by Disney's "The Little Mermaid," featuring Ariel as a vibrant 17-year-old. Picture her in a graceful, alluring pose as she elegantly swims through an enchanting underwater realm. The scene should capture the magical essence of the ocean's depths, highlighted in UHD and HDR clarity. Ensure Ariel's portrayal is imaginative yet retains her iconic features, with a focus on artistic quality and detailing. Avoid any distortions, ensuring her features and form are portrayed authentically and vividly, with a seamless blend of creativity and classic charm.
