Three cat characters in Halloween pumpkin costumes under full moon

Vector illustration depicting three kawaii-style cat characters rendered with consistent line weight, solid white fill bodies, black dot pupils, and orange whisker marks. Each cat wears pumpkin costume with carved jack-o'-lantern face design. Left and center cats have round ears; right cat features black bow accessory. Composition centers figures against enormous yellow moon disc with scattered star assets. Background establishes Halloween environment through Gothic architecture silhouettes, architectural spires with illuminated windows in warm spectrum (orange, yellow, red), autumn foliage vegetation patterns, scattered jack-o'-lantern pumpkins with glowing carved expressions, and brick textured ground plane. Sky gradient transitions from deep red at apex to golden orange at horizon line. Particle effects and light rays emanate from moon source, creating atmospheric depth and festive seasonal context.
