A masterful Halloween-themed artwork featuring Scooby-Doo and Shaggy in a cartoon style! amidst a haunted atmosphere with glowing jack-o'-lanterns and spider webs. The background should be a dark, misty forest with eerie trees and a full moon hanging low. Lighting is crucial, with warm orange hues from the pumpkins and a subtle blue glow from the moon. Shaggy's iconic green shirt and Scooby-Doo's matching collar stand out against the dark backdrop. The overall composition should convey a sense of bravado, as if they're ready to tackle any ghostly mysteries that come their way!
