Maybe not the doctor but it certainly improves the drawing skills. This is a scheduled post in which I'm sharing a sketch today that I did of my hand, using charcoal pencil and a paper stump.
I hadn't used charcoal since my primary school days and had horrid memories of the mess; all over the paper, my arms, face and even legs - don't ask!. These days you can buy it in pencil form so much less messy to hold and a paper stump is a great substitute for your finger to blend with. It's basically a pencil made of a paper block - I think. Anyway, here's the sketch.
The proportions and angles were not measured exactly, hence the width of the thumb, because it was the process of using charcoal I was most interested in. However, it turned out quite well and I can say that I really enjoyed using this medium. So much so that I've done another couple of sketches with charcoal which I'll share later.
