I added a piece of vellum behind the ghost so you couldn't see the candle as much and to help diffuse the light. I also put a bit of Wink of Stella over the ghost so it shows up a bit better in the daylight.
Here is it with a spooky 3D tree from Happy Hauntings. It makes a cute little scene.
I also made a mini one that could be used as a small treat bag. They were really easy to do, and fun too!
