First of all, you need to determine your composition, determine the position of the whole figure outline, and distinguish the head, trunk and limbs. This step does not need to be too detailed, but it is convenient for you to define a range to grasp the proportion of characters.

Then continue to calibrate the outline, determine the position of the five senses of the characters, and draw a general clothing trend.

At this time, you have a sense of the whole picture, and you can start drawing details, depicting hair, facial features, fingers and so on.

Finally, under a certain natural light, the characters have a bright side and a dark side, and the bright side and the dark side are distinguished. If the pencil is lightly colored in the dark, your character will be three-dimensional.
