A portrait of a woman with long blonde hair wearing oversized, angular light pale soft pink sunglasses, exuding a bold and confident attitude. The woman is dressed in a luxurious soft pale pink fur coat, partially covering her face, creating a sense of mystery. The minimalistic white background contrasts with the dramatic textures of the fur and the sleek lines of the sunglasses. The lighting is soft, casting gentle shadows that emphasize the strong, glamorous vibe of the image.

A girl wearing colorful clothes and a hat is riding her bicycle on the road, with a white cat walking beside her in front of Mount Fuji. The background features vibrant colors and a sky filled with clouds. In the style of psychedelic illustration, flat illustration, editorial illustration, and detailed character design, it's an extremely beautiful painting with a colorful palette and a touch of whimsy.
