[Typography] Hand-painted dry-brush cream script kicker, heavy angled brush display title with a cream outline and shadow, ribbon labels in condensed sans, small icon captions in light sans. [Subject] A white ghost in a witch hat holding a small lantern at upper left, a hilltop haunted house with pointed towers under moonlight, bats crossing the frame, and along the ground a stone wall, crooked headstones, glowing carved pumpkins, a smiling ghost character, a black cat and a lantern by a gravestone. [Lighting & Mood] Cool moonlit blue-violet against hot orange accents, fog rolling between the gravestones, spooky but commercial. [Details] Clipped ribbon ends, tiny pumpkin ornaments, sparkle specks, soft vignette, clean edges around the empty center panel.
