Prompt
A whimsical Halloween-themed sticker-sheet illustration on a saturated marigold-yellow background, arranged as a loose grid of pop-graphic icons: a smiling green frog wearing a carved pumpkin as a hat, a turquoise butterfly with patterned wings, a purple cartoon cauldron with a face, a magenta-and-pink lava lamp with a hand floating inside, a melting blue candle topped by two googly ghosts, a smiling daisy, a polka-dot mushroom house, a pair of grinning sunflowers, a winged kawaii bear, and a fanged cactus in a striped pot. Style is 1970s psychedelic-pop blended with kawaii: thick black ink outlines of consistent weight, flat saturated fills in lime, magenta, lavender, electric purple and orange, no gradients, light stippled shading for volume. Composition is flat and frontal with each object isolated like a die-cut sticker. Mood is playful, vintage, slightly trippy, retro spooky-cute.
