Miku :)

The main subject is an anime-style character with long blue hair and twin tails, who performs a series of exaggerated facial expressions and hand gestures in a looping animation. The character begins by covering her face with her hands, then reveals a wide, smiling expression, followed by a close-up of her eyes being pulled wide open, a distorted face with multiple eyes, a contented smile with hands clasped, and finally a direct gaze with a gentle smile, all against a plain white background.
