Not Part of a Sketchbook, Technically

But here is the progress thus far of the mural I am doing in the munch's room. It's Calvin&Hobbes sleeping in a tree... very simple. Unfortunately, because I did the initial outline in pencil, it's taking FOREVER to do the needed amount of layers in the yellow to cover the marks.. sigh. Once I get tired of layering, I add another color just so it feels like I'm making some kind of progress... then I go back to the yellow and layer some more...
