She is also wearing a black scarf with white polka dots tied around her neck like an ascot. • Setting & Context: The background suggests a sunny, coastal location with a deep blue ocean/sea visible behind her.

One cat is a sleek black feline with emerald green eyes, the other is a fluffy ginger tabby with white paws. They are perched near the neon-lit storefronts and glowing billboards, surrounded by vibrant city life: crowds of people, bright taxis, and street vendors selling local food. The scene is alive with colorful reflections on rain-slicked pavement, atmospheric mist, and dramatic lighting from neon signs in Chinese characters. The artistry should blend urban realism with a touch of whimsical charm, focusing on the cats' expressive faces and the dynamic ambiance of Nathan Road at night.
