The most important thing to draw a smile is the eyes and mouth. Step one, draw a smiling eye! Simply put, it is this curved crescent-shaped eye. Don't force your eyes to be big for the sake of them. Simple big eyes will look dull and can't reach Chengdu with a smile. Instead, we will draw them flat. The head of the eye is higher than the tail of the eye, and the pupil is full of the lower orbit. There will be a smiling eye feeling that squeezes the eyes because of a smile, which will look very vivid.
At the same time, considering that the character is smiling, Risolius will exert his strength, so his eyes will have an upward supporting force, thus forming a lying silkworm when smiling. With qualified smiling eyes, you won't be so stiff when painting. As for the mouth painting, it is basically a crescent-shaped painting.
