Add Some Drama: Use Emotions!
Don’t forget to add emotions to your main character. May it be a cheeky grin or raised eyebrows, whatever variation you put on his/her features can help in giving him/her more character, life and personality. Unless you intend your main character to be totally expressionless and still, it’s rewarding to give it emotions. If they are scared or angry, you could emphasize this using the next step.
Add Some Life: Use Color!
Assuming that you would be displaying strip on your Web site or you would be printing it off from your colored printer, it is best that you add color to your work. This would give people variety to look at. It also helps give more life to your cartoon. Remember, since cartoons are not always depicting reality, having a non-realistic colored character is all right, take the Pink Panther for instance.
Add Some Depth: Use Shading
Adding a few strokes of shading would go a long way for cartoons. Your readers’ minds would fill out the blanks. Thus, you do not really have to draw each strand of hair, if your character has a hairy leg. Just place enough strands and some hints. Their imagination would do its job and join the dots. In fact, this is extremely effective and would allow your readers to develop their imaginations.
Add Environment: Use A Background
Like shading, this doesn't require too much detail. Placing a pyramid shaped outline if your character is in Egypt would do fine. You do not have to draw the Sphinx, unless your storyline requires it.
Let Them Speak: Add Some Caption
The final touch in giving your character life is by letting is speak. It doesn’t matter if it’s an animal or human. They do speak. Decide whether you are going to put the lines on a speech bubble or simply below the cartoon box.
