How to Draw Lightning. Lightning is an exciting subject for artists. Every lightning streak through the sky seems to be unique, organic and flowing. When we try to draw that kind of an image, we can choose between the cartoony style--a simple jagged-edged curve of a line--or we can take our time and make it look more realistic.
Freedom of movement is the key. If you get too heavy-handed, the lines will look less like real lightning.
