Create a beautifully atmospheric illustration of a cat from 'The Cat Returns', depicted in a style akin to that of Makoto Shinkai. The scene should capture the cat elegantly posed on a city rooftop at twilight, with the sky painted in vibrant hues of pink, orange, and purple. The cityscape below is detailed with shimmering lights and bustling streets, reflecting Shinkai’s signature focus on luminous, intricate backgrounds. The cat, sleek and mysterious, gazes contemplatively at the sprawling urban landscape. This artwork should combine the whimsical charm of the character with the poignant, ethereal beauty typical of Shinkai’s films."
