I go through a fazes where I try to teach myself anatomy drawing from the couple of books I have on the subject. Here is one of my attempts to draw a skull. It was done with a Pigma Micron pen.
By the way, I added a Simon game on the right under my Songs For Wasting Paper. I remember when one of my cousins received Simon for Christmas. I was ridiculously bad at playing at it. Now some 30 years later I'm just as awful at it. Have fun!
