A caricature is either a portrait that exaggerates or distorts the essence of a person or thing to create an easily identifiable visual likeness. Caricatures of politicians are commonly used in editorial cartoons, while caricatures of movie stars are often found in entertainment magazines. Derived from the Italian word caricare, meaning to charge or load, caricature essentially means a loaded portrait.
Choose the person you are going to caricature.
Get out your pencils.
Draw a small body with an outfit that the person you are drawing would wear when doing a hobby
Draw a big head exaggerating the shape. For example, if the forehead of the subject is wide, emphasize this by drawing a wider than normal forehead. If it is narrow in comparison to the average forehead, draw a narrow forehead.
Draw the hair. If the person has curly hair, make your drawing have really curly hair; if they have long hair, draw it down to their toes; etc.
Draw the eyes in vibrant colours if the person has long eyelashes, do them huge.
Draw the nose. The nose is pretty straightforward, big or small, lumpy or straight, etc.
Draw the mouth. The lips are quite easy, plump, thin, straight etc. If the person has good teeth, exaggerate the straightness; if they have big teeth, give them buck teeth; if they have crazy teeth, cross them right over. Just go crazy.
