The first phase of the work is to define different proportion of all the character. Children from the cartoon "South Park" have a head of a diameter larger than the width of the body. That is, if the diameter of the body equals 4 cm, suitable head should have a diameter of 6 cm. However, drawing Eric Cartman is an exception among the rest of the characters.
In order to make a standard template for all the characters, just find the object having the appropriate range of the base. Use pencil and calculate the diameter after drawing a square the width of which is two-thirds the diameter of the circle.
To draw oval eyes in the middle of the face, you can use coins. First circle them and then "cut" corners. The legs are formed by separating two ovals at the bottom of the square, which was to become the child's body from "South Park."
Next you will see individual features. For example Stan Marsh wears a hat on his head. Take a plate or a disc to draw a circle that is something round with a large diameter. Headgear of the other characters can be created using round and square objects and all other elements of the character’s clothing can be drawn by hand.
When the sketch is ready, you need to delete all the auxiliary line and colour of the resulting image. Then gently apply the contour black.
