You could say that drawings of that kind should be very accurate and certainly for realistic representation that's true. But drawings are commonly exaggerated into cartoons or caricatures. Some artists distort figures or faces to make a point or to reinforce emotion. So I'm not saying that all drawing should be rigidly representative and be absolutely realist. On the other hand, being able to draw a face, or figure, or an object, giving it not only a recognizable appearance but also providing the illusion of weight and the appearance of occupying three dimensions is an exceptionally useful set of skills.
Most mornings I begin studio work with a few graphite drawings, usually on toned paper. Sometimes while surfing the net for morning news I pause a story or a video and sketch one of the faces or some of the figures in the story. But more often I draw from memory or from other materials, or life. Lately, I've been drawing both in the mornings as my warm up and later in the day as a learning tool. Off and on I've been copying drawings by the great Al Dorne as well as others that were published in the Famous Artists School course from the mid-20th century. Here are a couple of pages from my sketchbook.
