It has already been determined some of the positive elements of good description (see Description Part 1: 3 Elements of Good Description), but there are some pitfalls of description to be aware of as well. Here a 6 to keep in mind.
1. Never use description that will serve the character, instead use description that will serve the story. That means don’t throw in description for the sake of just having it. If the description doesn’t enhance or move the story forward then cut it out. It will only serve to be a distraction.
