Read over what descriptions of this character you already have—if its a character from your favorite fandom, read some fanfiction, or whatever descriptions you’ve written so far if it’s an original character.
Then write a paragraph describing that character.
But as you write your description, recall the most memorable traits about them, both from memory and from the stories you read before, and select a few that you see being described most often—like their hair color, their eyes, or a particular habit. Then, do not mention that trait at all. Think of whatever other means you can to describe them.
And don’t just avoid certain characteristics! Also watch what words, phrases, and images you’re using to describe them. It’s really easy to begin to rely on less-than-fresh phrases and imagery, because they immediately come to mind. But are those the most interesting words you can think of? Could you cut out that image and replace it with one that you’ve never used before? How succinctly can you describe them, while still making them recognizable, and the writing compelling?
It will help you develop new ways of thinking about physical imagery!
This is the story of how a certain kingdom came by its rather unusual princess.
It begins with the Sultan.
In his youth, he was hotheaded and prideful as could be. He lived to fight.
His arrogance provoked many wars, and made him many enemies.
He who eats fire, craps sparks.
(translation: Don’t be surprised at the outcome when you do something stupid.)
And for those of you that are uncultured on art history, this painting is every literal Netherlandish proverb happening all at once.
