Black-haired girl ties ponytail with hair tie in mouth at tennis court
The image is a Japanese anime-style illustration of a black-haired girl standing on an outdoor tennis court, raising both hands behind her head to tie a ponytail, her hair gently lifted by the wind. She has her eyes closed and a slight smile, cheeks slightly flushed, holding a hair tie in her mouth. She wears a white short-sleeved sports shirt with a small blue emblem on the left chest, and dark blue sports shorts with white vertical stripes on the sides and a small pattern at the hem. The background features a green court, white lines and fencing, trees in the distance, and bright, soft lighting. The composition is a half-body shot with delicate lines and fresh colors.
