Mid-Century Gouache Illustration of Stylized Cat with Turquoise Yarn

Full prompt

A whimsical mid-century modern gouache illustration designed in a 9:16 vertical poster format, celebrating 1950s geometric design and clean screen-print textures. In the lower half of the composition, a stylized, angular black-and-white cat arches playfully atop a warm teak credenza, batting at a bold turquoise-blue yarn ball. A crisp, rhythmic graphic zigzag of blue thread loops safely across the credenza top without tangling. Rising into the tall vertical upper frame, potted monstera leaves with clean cutout silhouettes and an abstract geometric wall hanging in mustard yellow and olive green fill the background. The vertical balance preserves generous open space overhead, making it an ideal full-screen phone wallpaper.
