All right, not great literature. But I'll wager anyone who reads it forms a strong picture Marcus Amelianus. In fact, however, I said very little about him. Only that he's fat and bald with a fervent dislike of getting naked in public. The rest I left to the imagination.
Description is more than simply building an image.
It sets the mood, coloring the action and the characters, creating the backdrop your plot moves against. Like a river, it gives direction to the story. Don't be afraid to experiment, to paint outside the lines. And above all else, have fun with it. Writing description allows the poet in all of us to slip out now and then.
