1. Draw the outline of the head: First, gently draw the basic shape of the head with a pencil, including the top of the head, chin and cheeks. Pay attention to keep proportion and symmetry.
2. Draw eyes and masks: Next, outline the details such as eyes and masks with thin lines. Axside's eyes are bigger and need to be described carefully.
3. Fill color: After the draft line is completed, you can start filling color. Axside's main colors are black and red, but there are some other bright colors dotted with it.
4. Add shadows and highlights: Finally, after finishing the basic coloring, you can add shadows and highlights to enhance the three-dimensional effect. Note that the position of shadows and highlights should be determined according to the position of light source.
The above are simple steps, of course, the details need to be adjusted according to your own painting skills. I hope these can help you!
