After trimming for a period of time, I settled down what I thought and learned, and began to continue studying and working, drawing a hand to find out the feeling.

01. Needle and pen draw the draft.

02. Use a lighter marker to draw light and shade.

03. Use deeper colors to deepen light and shade changes.

04. Use darker colors to distinguish parts of different colors.

05. Use dark gray to deepen the dark surface and depict the details.

06. Add color to the part, pay attention to light and shade changes and leave highlights.

07. You can use a needle pen to trim the details again, and add a proper amount of decorative patterns and text to enrich the picture.
