These are some early sketches I have done of Jimmy the Goose, the main character of the story

The yellow gas turning the townspeople into ghosts as a screen print

in this scene the boy josh is chasing his dog around the graveyard, the dog is trying to tell josh the names on the graves are the townspeople

The same image just darker

This is from the Goosebumps project, in this scene the ghosts have surrounded the children
