a cartoon girl with red eyes and white hair giving a thumbs up

Create a looped animation featuring a character with white and red hair in two pigtails, wide red eyes, and a mischievous grin. The character should blink occasionally, with the eyelids closing and reopening smoothly. The background is a cityscape with tall buildings silhouetted against a reddish-orange sky, indicating either sunrise or sunset.As the character blinks, their expression should slightly shift to intensify the mischievous grin, adding a playful or slightly menacing vibe. The background should have subtle movement, such as a slight shimmer in the sky or the silhouette of birds flying across. The animation should also include small details like the character's hair slightly moving as if a gentle breeze is passing through.
