Chibi Witch Halloween Party Poster

Professional Halloween party poster, vertical 9:16, stylized cartoon illustration. [Colors] Searing orange (#F5821F) sky graded into deep magenta shadows, purple (#7B2FBF) magic glow inside the stone arch, black ink silhouettes, clean white star accents. [Layout] Oversized brush headline across the top with a tilted witch hat accent, a short subtitle beneath, a monumental gothic archway dominating the center as a glowing portal, and a bracketed call-out line stacked above the date at the bottom. [Typography] Aggressive dry-brush display type with rough torn edges, small hand-drawn sans for support copy, thin starred date line. [Subject] A chibi witch girl in a purple dress, striped stockings and pumpkin-buckled hat strides out of a glowing violet portal, one hand open toward the viewer and the other gripping a broom; spiderwebs cling to the arch, a lantern pumpkin hangs on the left, a friendly ghost floats right, gravestones and carved pumpkins line the wet steps. [Lighting & Mood] Strong portal backlight, warm orange spill, mischievous adventure energy. [Details] Bats in the upper air, sparkles, cracked stone steps, scattered falling leaves.
