Left and right profiles of the same model skull, sketched on two consecutive evenings using a thick white pen for initial lines, then dilute grey ink to add form/shadows, and water-colour for background. This skull’s been a favourite and familiar subject since I started sketching (see below for earlier attempts over the years), I bought it for £1 at a flea market when I was about ten! It’s always a challenge to draw, the many ridges, curves and cavities are as rich and varied as a landscape, and it’s great for exploring shade and form. Here’s a similar model if you fancy having a similarly patient life/death model to sketch.
