There are a couple of stickys in the story forum for advice to help you with your story.
Important points are:
Dont use the same team as any other recent story in the section.
Use good grammar and proper layouts to make people want to read.
Some plot twists are good to grab the readers attention.
Play at least 10 games of your save before you turn it into a story. You will be amazed how many stories dont make it past the first season.
