A painterly digital illustration of a sleeping orange tabby cat curled on a sunlit windowsill. The style features loose expressive brushstrokes, visible texture, and soft color blocking that mimics gouache or acrylic painting. The cat is rendered in warm amber and cream tones with simplified facial features, while the cityscape outside is painted in muted blues, grays, and beiges. A glass vase with dried flowers and stacked books add domestic detail. The composition centers the cat horizontally across the windowsill, with vertical window frames creating structure. Soft diffused daylight fills the scene, casting gentle shadows and creating a hazy urban atmosphere. The genre is contemporary everyday illustration with a peaceful, nostalgic mood, emphasizing quiet domestic comfort.
