Square Halloween illustration, a close-up of a group of characters gathered closely together and gazing directly at the viewer with fascination: a young witch in a large pointed hat, a little imp with red horns and tousled hair, a pale vampire with pointed ears and a high collar, a semi-transparent ghost, and a black cat with golden eyes. All of them have wide-open eyes and a surprised, almost hypnotized look on their faces. Dark purple background, glowing magical spirals and sparks swirling around the characters. Dramatic orange-purple lighting, a detailed fantasy book illustration, mysterious, slightly eerie but not frightening atmosphere. The characters are large, their faces are clearly distinguishable, no text.
