Okay, now that I've gotten planking out of my system, we can get back to bidness. Here's some pencil from my late teens. The original is noticeably lighter than what you see here. When I was fiddling around with this post-scan I hit ye olde auto-adjust on the colors and everything just popped. It really brought out all the original detail from this old drawing so I ran with it.
As for content, methinks this has something to do with an artwork I often stared at as a kid in California. It was in this book called The Mind my parents had in the living room. The artwork in question was a painting done by a schizophrenic depicting their skull split open lying in a grassy field and you could see different compartments inside. Each compartment showed scenes, memories, abuse, insecurities and the like from their life experiences. I remember being obsessed with that book and that painting in particular. As for my drawing, the head seems hollow with all the interesting stuff on the outside. Perhaps the inside was gutted by fire, as there are some small flames still burning.
