A medium shot, eye-level anime illustration of a 17-year-old girl standing on a sun-drenched beach. The girl has long, flowing black hair that reaches her waist and is wearing a vibrant, elegant blue dress that billows slightly in the sea breeze. She is posing with a "burikko" expression, tilting her head slightly with a cute, exaggeratedly sweet smile and her hands pressed together near her cheek in a shy, playful gesture. The background consists of a pristine white sandy shore meeting the crystal-clear turquoise waters of the ocean under a bright, cloudless blue sky. The lighting is bright and natural, creating a high-contrast scene with vivid colors and a cheerful, innocent atmosphere, utilizing a clean art style with sharp lines and luminous highlights on the water's surface.
