Cheerful Halloween Mall Event Poster

Professional Halloween mall event poster, vertical 9:16, bold flat graphic illustration. [Colors] Saturated grape purple ground (#7B4BC8), acid yellow (#F5E14A), orange ticket panel (#F26B21), mint green bat (#5FD3B4), off-white ghost. [Layout] Top half held by two stacked oversized brush-script headline rows set on a slight diagonal; a black cat walks the right edge of the second row. An orange torn-ticket block fills the lower half with three numbered vertical steps, closed by a dotted yellow ticket stub at the very bottom. [Typography] Rough dry-brush display type in yellow with heavy black offset shadow, small clean sans for the step descriptions, black on orange for maximum contrast. [Subject] Cheerful white ghost peeking from a star, small mint bat, black cat with arched tail, glossy orange paper panel with torn deckled edges. [Lighting & Mood] Poster-flat with no gradients except a soft glow behind the ghost; lively, high-energy, community-activity tone. [Details] Hand-drawn number glyphs 01-03, pill-shaped highlight behind the middle step, diagonal motion strokes, wide margins for brand lockup at top.
