Spooky Halloween Cocktail Night Poster

Professional Halloween bar-night poster, vertical 9:16, dark-fantasy digital painting. [Colors] Black-violet base (#120A1E to #3B1560), smoke in electric violet (#8C3FE0) and magenta, drink in molten orange-amber (#FF8A1E to #FFC85A), castle windows in gold. [Layout] Thin gold rule with the event name at the top, a towering plume of smoke shaped into a grinning jack-o'-lantern face occupying the upper half, a coupe glass on a rocky ledge at center, castle and moon at the right, an ornate mirrored title band across the lower third, detail rows beneath. [Typography] Elegant gothic display with pointed spurs and a long swash, a mirrored glow duplicate beneath it, small gold sans for schedule lines. [Subject] Crystal coupe of glowing amber cocktail with a dried orange wheel garnish, smoke curling upward into a carved pumpkin face; bats circling, dead branches framing the left. [Lighting & Mood] Low-key with a single hot glow from the drink, theatrical smoke, mysterious and premium. [Details] Rock ledge, distant pine silhouettes, thin decorative frame lines, fine gold star specks, 'Spooky Party' kicker.
