Why did the anime character's entire mouth move to the side of his face when he was talking? I can't see the entire mouth from the side? Isn't it very surreal for an anime character to reveal their side profile and speak with their entire mouth on the side of their face? Why did he draw it like this? Why did he draw it like this?

This problem involved one of the common techniques of anime character design: facial distortion.

When anime characters talk from the side of their faces, their mouths are usually twisted to the side of their faces to make the characters look more lively and interesting. This distortion can be achieved in a variety of ways, such as adjusting the position of the lips and tongue or through the movement of facial muscles.

Face contortion could make the expressions of anime characters more realistic and rich, and at the same time, it could make their appearance more in line with the principles of ergonomy. However, it was important to note that if the facial muscles were overly twisted, it might cause the character's facial expressions to become unnatural and might even affect their health.
