Spooky Halloween Full Moon Clouds Replace

Create a spooky Halloween scene with a full moon and dark clouds in the background. Replace the original character with a shadowy figure standing on a hill, shrouded in a cloak. The graveyard should have gravestones with generic symbols rather than text, and include a variety of pumpkins, some with creepy faces and others plain. Add eerie bats flying through the sky and ensure there's a misty, atmospheric vibe with patches of green moss scattered across the ground.
