1. Draw the outline of Guan Yu's face, highlighting his heavy eyebrows and beard and chin.
2. Draw Guan Yu's hair and headdress. Hair is black and straight and often tied up. The headdress is red tassel.
3. Draw Guan Yu's armor and weapons. The iconic green robe and red armor should be described in detail, and the Qinglong crescent moon blade should show a sense of weight and sharpness.
The above steps are for reference only and can be adjusted according to personal style and preference.
