“Do not allow yourself to get discouraged. Every headanyone draws depends on construction, just as muchas every building, every car, every other three-dimensional object does. This is what the artist’s jobreally is in learning how to construct things in threedimensions on a two-dimensional surface. We have tothink of each thing we draw in its entirety and see howits dimensions appear to us from a particular viewpoint.Representation in three dimensions calls for knowledgeand study. But such knowledge is no more difficult thanthat required in any other field. No matter how greatyour talent, talent has to work with knowledge to doanything well. When the search for particularknowledge becomes pleasant as well, half the battle iswon. Construction need not worry you; it comes withpractice.”Andrew Loomis, Drawing the Head and Hands
Remember you are not depicting,say, your face. Instead, you aretrying to faithfully record the linesyou perceive. In other words, firstthere is perception -- try to stopmaking a whole out of the parts.Instead say: I am looking at theshape of the edge of this thing,and that thing happens to be anear, and look at where you seelines, and then try to get them onpaper. Drawing is all about seeing.
