How does Zeta draw?

First, describe the head of Zeta Altman roughly, and then describe the details of the head step by step after sketching the outline. The head needs to draw Zeta's head logo and facial features, and the face needs to draw a mechanical feeling. Draw the neck and arms gradually from top to bottom. Compared with the neck, Zeta's arm is more complicated, and the line feeling and muscle bulge of the arm should be drawn.

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, we have to do a step to draw shadows for finishing treatment. Shadow processing can make Zeta Altman's three-dimensional sense stronger, and the shadow part can be painted on the arm, chest tag, neck and other places. You can write the following words after painting the film. You can pay attention to the style of the text, and the hollowing out in the middle is artistic.
