Simple pen drawing requires the shape of the object, structure, line, etc. to streamline as a principle, that is, the object to be depicted should be highly generalized and simplified image, the following for the simple pen drawing drawing techniques:

One, observation, analysis.

Before all the work of painting, the first task is to depict the object of comprehensive observation and analysis. Before the pen, carefully observe the object's morphological characteristics, size and proportion, the relationship between the whole and the local, dynamic expression, etc., to grasp the object's internal and external links, and strive to achieve the whole heart, there are details, there are characteristics.

Second, association and exaggeration.

After the observation of the object, we should think out of the box to find the basic shape to match the shape of the real object, or from the real object to summarize the basic shape, simplify the complexity of the objective object. For example, a basketball is round and a rugby ball is ellipsoidal.

From the basic shape, the use of appropriate exaggeration, the object's physical features exaggerated, so that the features are moderately enlarged, so as to create a thousand variations, intriguing sketch works. For example, the proportion of a child's head to his height should be slightly larger than in reality, his eyes should be drawn larger than in reality, and his little face should be drawn fatter.

Third, grasp the characteristics.

The basic shape of the shape is limited, however, everything in the world is indeed infinite; infinite number of objects with a limited number of modeling to summarize and generalize, there will inevitably be some of the object modeling is the same. For example, the TV is rectangular, picture frames, closets, windows, doors and other objects are also rectangular, the overall image of this class of objects, we must find the details of the object features and local characteristics.

For the overall shape and local features are identical objects, it is necessary to use other objects to set off, in order to distinguish them. For example, eggs and duck eggs, basketball and soccer, etc., the object shape characteristics are identical, such as the existence of a separate can not distinguish between these items, so you need to use the hen and duck, basketball goal and soccer goal and other related things to set off.

Four, the basic shape of the combination

The use of different basic forms of organic combinations, the formation of objects. The use of basic shape, the overall characteristics of the object to generalize and summarize, refine the complexity of the form, and then local details of the specific carving; with the help of the object skeleton line, first draw the skeletal dynamics and morphology, and then local details of the carving; the combination of the first two methods, and then the local details of the carving.
