Cezanne once wrote a friend saying "May I repeat what I told you here? Treat nature by the cylinder, the sphere and the cone..."
His notion that nature could be rendered solidly using basic geometric forms is part of what caused Cubists like Picasso to paint using a twisted perspective. A twisted perspective means that you depict an object from more than one angle simultaneously. The effect in Picasso's case was that the images look like they are broken up reflections in a shattered mirror. This lead to one of his contemporaries Henri Matisse saying that the Cubist paintings looked like they were painted with little cubes.
Create a Cubist inspired portrait using basic geometric forms to break up the space. Image a mirror being broken and distorting your reflection. Advanced option: add color or use charcoal.
