This drawing shows a human skull cut open from the side. The jaw is open, and you can see the teeth, tongue, and the inside of the throat. The brain is exposed, with the skull’s top peeled back to reveal its folds and texture. The artist used shading to show depth, making the bones look solid and the soft tissue look smooth. Tiny lines and dots create shadows, giving the drawing a realistic feel. If you like this style, look up cross-hatching next.
