The first picture of the main body is still a little pouty. There is a simple test method, that is, relax your mouth, put your index finger on the tip of your nose and chin, and see if your upper lip and lower lip are behind your index finger in turn. If it is, it is the standard side face. If it is next to the index finger, it is a convex mouth. The subject can try.

Look at the picture. On the right is the standard side face.
