1. Use the pen quickly and don't stop. The power of using a pen lies in the proper density of points, lines and surfaces.
2. Pay attention to the overlapping relationship between colors, the change and collocation of colors.
3. Draw an object as a spiritual thing.
4. Novices who just started drawing with markers will draw the basic light and dark tones in the picture with cold gray or warm gray markers.
5. The coverage of markers is not strong, and light colors cannot cover dark colors.
