Halloween Trick-or-Treat Night Poster

Professional Halloween trick-or-treat poster, vertical 9:16, painted vector illustration. [Colors] Deep indigo violet (#2B1B54) to near-black sky, luminous honey moon (#F7A81B), orange (#F26A21) display type, pale lilac mist. [Layout] Headline block filling the top quarter across the sky, an enormous moon disc centered behind the hero, a silhouette horizon along the lower third, and a three-line event footer at the bottom. [Typography] Dripping brush-script headline with small ghost and bat accents, condensed uppercase English subline, thin light sans for the schedule and venue. [Subject] A black cat with oversized amber eyes and a curled tail sits on a dark rock in the foreground; behind it a haunted house with lit gothic windows perches on a hill, graveyard crosses and a picket fence along the ridge, bare branches hanging into frame from the top corners. [Lighting & Mood] Moonlit backlight, inky shadows, mysterious but friendly. [Details] Layered mist bands, distant pine trees, tiny bats circling the moon, crisp silhouette edges, subtle star specks.
