Avoid creating a back story that is completely detached from the current situation of the character. For example, if your character is in a fantasy world fighting dragons, their back story should somehow connect to this. Maybe they were trained by a dragon slayer in their youth. Also, don't make the back story overly tragic just for the sake of it. It should feel natural and help in understanding the character. And be careful not to introduce too many characters in the back story that have no real impact on the main character or the main plot.
One common mistake is making the back story too long and complicated. Keep it concise and relevant to the main story. Another is having a back story that doesn't match the character's actions. If your character is supposed to be brave but their back story makes them seem cowardly, it won't work. Also, avoid clichés. Don't make the character an orphan just because it's a common trope.
Avoid starting with too much backstory. For example, don't begin by explaining the entire history of the character's family tree. Readers usually want to get into the action or interesting part right away.
One common mistake is creating a static character. A character that doesn't change throughout the story is dull. Readers are often interested in seeing growth or a transformation. For instance, if a character starts as a coward and ends as a coward without any development in - between, it's not engaging.
Don't make the plot too confusing or hard to follow. Keep it simple and engaging.
One common mistake is making your self - insert too perfect. In the Twilight world, even the main characters have flaws. So, give your character some weaknesses. Another mistake is ignoring the established lore of the Twilight series. For example, if you write something that goes against the rules of vampire or werewolf behavior, it can seem out of place. Also, don't make the story all about your self - insert. The existing Twilight characters should still have important roles and development in the fanfiction.
Avoid ending abruptly without resolving the main conflict. It leaves the reader feeling cheated. For example, if it's a battle story and the fight just stops without a clear winner.
One common mistake is ending too abruptly. It can leave the readers feeling unsatisfied. For example, if you're writing a long adventure story and suddenly end it without resolving the main conflict, it's not good.
Over - explaining can also be a mistake. Once you've made your point, stop. If you keep going on and on about the meaning of the ending, it can take away from the impact. Let the readers draw their own conclusions to some extent.
One big no-no is having a confusing plot. Make sure your story flows logically and readers can follow easily.
Don't make the ending too rushed. If you've built up a complex plot, take the time to wrap it up properly. A rushed ending might leave the reader feeling like they missed out on something important. For example, if a long - running love story ends with just a quick 'they got married' without any real build - up to that moment, it can be disappointing.
One common mistake is splitting it too randomly without a clear logic. This can make the back story seem disjointed.
