How About The Internal Structure?
Next, you should think about the internal structure of your drawing. As soon as you have your chosen shape and you have drawn it on your paper, think about what you want to place inside. Visualize a design that you would want to place within your shape. There is basically no limit in choosing a design and there are different variations available for you to play and experiment with.
For instance, you can draw a smaller version of your outer shell’s shape. So, if you have a S-shape for an outer shell, then you can place a smaller S-shape inside. You can place only one or even a number of smaller S-shaped flames with different sizes and shapes inside. It is all basically up to you.
Add Some Color
Although flames can be drawn in both black and white, and color, opting for the first one would require mastery of shading. For beginners coloring is recommended. Doing this would give life to your drawing. So, add some color to your flame. Recall what the flame looked like when you lit up the match or when you lit up the lighter. If possible try to light a fire again, just to see the actual colors.
Observe closely. See the difference of the inside portion of the flame with the outside. If you look closely, you would see that the tip is colored blue, in most cases. The core also has this color. However, as you go farther out from the core, you would observe that hues of yellow, orange and red have appeared.
Use your imagination and try to blend these said colors in your drawing. Arrange them as how your model flame looked like.
