Halloween Candy Party Sticker Collage

Square social post for a Halloween candy party, 1:1, sticker-collage illustration style. [Colors] Grape purple background (#4B2270) with violet clouds, hot orange (#F5821F) and cream (#FBF3DF) accents, candy pink and lime highlights. [Layout] Stacked torn-paper banner at the top holding the wordmark, a bold headline bar beneath it with overlapping tag ribbons, the hero pumpkin and ghost occupying the center, and a tilted date plate with a ribbon at the bottom. [Typography] Heavy white display letters with a slight skew on an angled paper strip, chunky outlined headline with a thick white stroke, small pill-shaped tags in contrasting colors, playful rounded numerals. [Subject] A giant 3D grinning jack-o'-lantern with raised stubby hands, a small white ghost with open arms in front of it, two oversized spiral lollipops, scattered wrapped candies, crescent moon and stars; each element outlined with a thick white die-cut sticker border. [Lighting & Mood] Bright flat-lit pop-art energy, saturated and playful, party-poster vibes. [Details] Paper-tear texture on the banner, halftone dots, offset shadows, bat silhouettes at the corners, hand-drawn star scribbles.
