Specific steps:

1 First of all, we need to draw the outline of the flame. The flame has no fixed shape, so we can draw the root and bifurcation of the flame with curves, as shown in the figure.

2. After that, we drew a circle of flame outline in the previous step to show the contrast between flame temperature and light and dark, as shown in the figure.

3. Then we draw a small circle in the center of the flame, which is the core of the central temperature. Then draw a small flame floating on it, as shown in the figure.

4. Then we draw a bigger flame in the blank space on the upper right, and fly out to show the real flame more vividly, as shown in the figure.

Then we draw some firewood at the bottom of the flame and pay attention to the beauty of firewood. After all, a flame needs a fire source, so we can draw it as a picture.

6. After that, we drew some dots of different sizes around the flame, showing the exuberance of the flame, as shown in the figure.

7. Finally, we drew flames, mainly orange and yellow. When smearing, follow the principle that the center color is bright and light, and the edge color is dark and deep, as shown in the figure. You can draw a flame diagram according to the method of stick figure editing.
