Halloween drinks promotion poster, vertical, neon-glow night finish. [Colors] ink violet #140A1E, electric purple glow #8B3BFF, white type, grape and cream layers, faint cyan rim. [Layout] a script line at the top, an oversized brush headline below it, a small spaced line flanked by dots, the drink dead centre standing in rippling water, and a circular seal badge on the right at hip height. [Typography] thin neon script, thick grooved brush capitals with a light inner glow, small gold letter-spaced captions with dot ornaments. [Subject] a clear cup of taro and coconut drink with dark berry compote, whipped cream and crumble topping, planted in shallow water that mirrors the light; behind it an enormous carved pumpkin face blazes purple, with palm-frond silhouettes and low mist in the distance.
