Playful Spooky Ghost Halloween Party Flyer

Professional Halloween party flyer, vertical 9:16, flat vector illustration. [Colors] Saturated pumpkin orange #F5821F across the upper two-thirds, deep grape purple #5B2C83 hill mass at the bottom, ink black, bone white. [Layout] Type dominates the top half: an oversized three-line hand-brushed headline with a pinned speech bubble callout top right and a small spider dangling on a thread from one letter; a rounded purple ribbon with white lettering sits underneath; a castle silhouette breaks the left horizon; the mascot fills the bottom right; a QR block, stacked date and italic invitation line sit bottom left above a footer address bar. [Typography] Rough dry-brush marker display type in black, one chunky white alternate word, wide-tracked italic caps for the date, small circular badge lettering. [Subject] A friendly wide sheet ghost wearing a purple witch hat, smiling with two black oval eyes, one arm extended, tiny bats circling. [Lighting & Mood] Punchy poster-grade contrast, graphic and upbeat, playful spooky energy. [Details] Stipple texture inside the letterforms, halftone shading on the hill, orange circular costume badge.
