Start with the top of Zeta Altman's head, and then outline the outline and details of the head. Details of the head include signs on the top of the head, eyes, ears, mouth and facial lines.

Then draw the neck and the shoulders connected with the neck, and outline the lines and muscles of Zeta's arms, palms and hands from the shoulders. Don't forget to describe them. Then there is a symbol similar to "Z" on Zeta Altman's chest. In addition to the symbol, the upper body should also draw a sense of streamline of armor.

Finally, draw a shadow for finishing. Shadows are painted in black, so you don't need to draw too much. Behind the ears and arms are the key parts of the painting. The purpose of shadow processing is to make Zeta Altman more stereoscopic.
