Spooky Cute 3D Halloween Ghost Poster

Professional Halloween greeting poster, vertical 9:16, 3D cartoon render. [Colors] Deep violet-to-plum gradient sky (#2B1B4A to #4B2A6B) against a warm tangerine moon (#F2913D); ghost in creamy off-white, shutters in dusty mauve. [Layout] Upper third holds a thin gothic headline over a stone arch; the center is a diamond-paned window frame acting as a stage for the ghost; a slim date band and contact strip anchor the bottom. [Typography] Hand-brushed white calligraphic title with rough dry-brush edges, small spaced serif line above, thin condensed sans for date and venue. [Subject] Rotund 3D ghost with huge glossy black eyes, rosy cheeks and an open smile leaning out of a weathered wooden window, one mitten hand raised in a wave, gossamer sheet draping in soft folds. [Lighting & Mood] Cool moonlight rim from behind, warm pumpkin glow from below, playful rather than scary. [Details] Cobwebs strung across the shutter corners, three bats circling the moon, two wrapped candies at the base, faint brick texture in the wall.
