Create a comic book-style poster for a cartoon called 'Cryptic Cruiser

Create a comic book-style poster for a cartoon called 'Cryptic Cruiser'. The image should feature a mysterious van with a bright, haunted design, parked in a misty, shadowy forest. Show the silhouettes of four characters so that their faces are obscured, adding to the mystery. One of the characters is holding a flashlight, lighting the way in the darkness, while another is holding a map. Next to them is a large, shaggy dog, its ears pricked up as if sensing danger. In the background, outlines of spooky trees and an old, shadowy house are visible. The atmosphere should be dark and suspenseful, evoking a sense of adventure and the supernatural.
