A donkey is a member of the equine family, similar to animals such as horses, zebras and mules. These large animals have been domesticated by man for thousands of years, as they are durable creatures for riding or heavy loads. In order to accurately draw the head and face of a donkey, one must understand the subtle differences in this animal when compared with others of the same family. A donkey's ears stand higher and are positioned closer than that of a horse, while the snout tends to be shorter and stubbier. A picture of a donkey will assist you in realistically translating this animal's head onto a piece of paper.
Browse through a collection of donkey pictures until you find one that best suits the image you wish to create. You may want to select a picture that concentrates more on the animal's head than anything else, as this is the body feature you will be drawing.
Sketch the basic outline of the donkey's head, paying close attention to the proportions of the top versus the bottom. Use light pencil marks through this process so you may easily erase any erratic lines that you create.
Study the reference picture to learn how the different facial features of this animal are positioned. Sketch the shapes of the eyes, nose and mouth until these basic features form a face relative to the photograph. Keep the pencil marks light throughout this process, as well.
Check the sketched outline and features of the donkey drawing with the picture you are using as a reference. Erase any disproportionate features or erratic marks at this time.
Add more detail to the donkey's face, such as defining colour patterns and facial structuring. Take special notice to how the hair on the donkey's face flows over this particular bone structuring. Use small pencil marks to create this hair in the intended areas of the drawing.
Outline all of the defining pencil lines of your drawing with an ink pen. Carefully work the pen over all of the pencil marks until the drawing has been completely traced in ink. Let the ink dry on the paper for several minutes, then erase any pencil marks that still appear on the page.
Add shading elements to the drawing of the donkey's head to reflect a three-dimensional aspect to the animal. Take hints on lighting angles from the picture you are using as a reference. You may use either the pen or the pencil to shade, as each tool provides different effects.
