If it weren't for the drying time, this would have been a nice, quick little project!
I took the 12x12 canvas and covered it in gray & platinum paint. The trees are thin wood that were supposed to slide together to make a free-standing tree. I got it in the craft section at JoAnn Fabrics. I also learned that a toothpick fits in the slots nicely to fill them in. Painted them black.
I free-handed the headstones & the moon is a mix of platinum & black paints.
I may still go back with a deep green and add some tufts of grass.
