See, this is what happens when you check under the bed to see if a monster is really there. I don’t know if the monsters brought their own pillows to the party or if this is one lucky kid with an immensely comfortable bed (not anymore).
This is one of my kitchen-sink sketches that follow more or less the same pattern: start with pencil sketch, add watercolor, bits of colored pencil, ink the lines with a Sharpie, and tinker with the colors in Photoshop. I’m sure plenty of people work this way, but it took me a long time to grow out of the art school practice of practicing with one material until I knew it back to front.
Oh yeah, and this drawing was influenced by the hilarious “Monster Party” skit from “Mr. Show.” Look it up on Youtube before Halloween, you won’t regret it.
