Done some weeks ago, used Prismacolor Pencils, Crayola Crayons & color pencils, and oil pastels. All blue or shades of blue. Took three days. A monochromatic picture -they're fun to make! :] It's NOT for Halloween though if that's what you're thinking. My favorite part of this picture? The crying skulls and how the shading turned out. Something I could've done better: The main face. Thanks for viewing, enjoy.
