When writing, period, play to your strengths and focus on the flow of the story. Blend description and dialogue with the action, rather than separating long paragraphs of description and dialogue from the rest. The best writers can put you in the scene and help you visualize it without separating the different aspects of the writing. The biggest faux pas, so to speak, that I have seen in the stories in the archive is that when introducing a character (particularly a naked woman, there's a lot of those) is that they will stop the action to describe her--height, hair and eye color, and sometimes numerical measurements. While the description helps with visualization, it should be spread throughout, not centered in one paragraph. Those few stories that I have proofread and edited are usually guilty of this. And no where is this more crucial than in erotica, as description plays such a major role in the story.
