A large black cat wearing a tiny

A large black cat wearing a tiny antique key around its neck sits confidently on a crooked crescent moon. The moon is secretly an old gothic apartment building, with miniature arched windows, winding staircases, and tiny inhabitants peeking through emerald-lit curtains. One window contains a miniature storm; another contains a floating eyeball. Flat black silhouettes, emerald-green architecture, violet sky, pale yellow stars, sparse crimson accents. Japanese pop art fused with handmade risograph illustration, bold contour shapes, imperfect ink registration, decorative geometry, charming but slightly wicked, dense details balanced by generous negative space, no glossy 3D rendering.
