Use vivid descriptions. When Bella is thinking about staying or leaving, describe the world around her in detail. The sights, the sounds, the smells. It will make the readers feel like they are right there with her, experiencing the same emotions and dilemmas. Also, make sure to have good grammar and spelling to make your fanfiction more readable.
To write a good fanfiction, focus on character development. Show how Bella and Marcus would change as they interact with each other. Maybe Bella becomes more assertive under Marcus' influence, and Marcus becomes more in touch with his emotions because of Bella. Also, use vivid descriptions. Describe the settings, whether it's the dark and dangerous world of Marcus or the misty Forks of Bella's world. This will draw the readers in.
In some fanfictions, Bella Swan could be in a situation where she is not the only one making the 'If I Stay' decision. Her friends and family are also involved in some sort of magical or supernatural way. For example, they all get a chance to vote on whether she should stay or go, and this creates a lot of drama and interesting character interactions as they all have different motives and desires.
Another way is to join Twilight - related fan groups on social media platforms. There, you can ask other fans if they know of any great Bella Swan crossover fanfictions. They might be able to recommend some based on their own reading experiences. You can also check out blogs dedicated to Twilight fanfiction. These blogs often review and recommend different fanfictions, including crossovers.
You can start by searching on popular fanfiction websites like Fanfiction.net or Archive of Our Own. Use specific search terms like 'Bella Swan Salazar' to narrow down the results.
Research is key. Look into the 'Twilight' series to fully understand Bella's world and the 'The Vampire Diaries' / 'The Originals' universe for Elijah. When writing their relationship, start slow. Maybe they start as reluctant allies. As for the story's setting, you could choose a new location that combines elements of both their worlds, like a small town that has a hidden vampire coven and is also on the verge of being invaded by an ancient evil that only they can stop together. You can also add some secondary characters from both franchises to add more depth to the story.
A good fanfiction involving these two would require a strong conflict. It could be an internal conflict within Bella Swan as she struggles with her feelings for this new, very different character. Or an external conflict like they are both being hunted by a powerful entity. Build up the tension throughout the story, and resolve it in a satisfying way at the end.
Create a unique and engaging plot. It could be something like a mystery that involves both Bella's world and the world of Sons of Anarchy. Maybe there's a supernatural element from the Twilight side that is affecting the Sons of Anarchy gang, and Bella is the key to solving it. You also need to pay attention to the setting. Describe the gritty world of the bikers and contrast it with the small - town charm of Forks where Bella lives. This can add depth to your story.
To write a good 'si oc bella swan fanfiction', it's important to create conflict. This could be between your OC and Bella, or your OC and the other characters like the Cullens or the werewolves. Maybe your OC has a different view on the love triangle between Bella, Edward, and Jacob, and this causes tension. Another key aspect is dialogue. Write believable conversations between Bella and your OC. This will make the story more engaging and help the readers connect with the characters. Also, don't be afraid to add your own spin on the Twilight mythology. It can make your fanfiction stand out.
You should also think about the plot. For instance, the dragon could be in danger and the swan queen has to rescue it. This creates conflict and drama. Don't forget to add some unique elements to the dragon, like special powers or markings.
