Use vivid descriptions. When writing from Peeta's point of view, really describe how he sees the Capitol, the other tributes, and the arena. For example, if he's in a forested part of the arena, describe the trees in a way that reflects his mood, like 'The gnarled trees seemed to reach out like the hands of the Capitol, always grasping.'
Create unique and complex characters. Don't just rely on the existing Hunger Games archetypes. Give your tributes distinct personalities, motives, and backstories.
Use vivid descriptions. Instead of just saying 'the arena was big', describe it in detail. 'The arena stretched out as far as the eye could see, with towering trees that seemed to touch the sky and a murky swamp that oozed an unknown stench.' This will draw readers into the world you're creating.
Create unique characters. Even if they are from the existing districts, give them distinct personalities and motives that haven't been explored much. For example, a tribute who is an artist but has to hide it because art is not encouraged in their district.
One idea could be exploring Peeta's thoughts during his training in the Capitol. He might be sizing up the other tributes while also trying to figure out how to play the 'lovestruck boy' role to gain sponsors. Another could be his internal struggle when he realizes he has real feelings for Katniss while in the middle of the Games, and how that affects his decisions.
Use unique characterizations. Instead of the typical Hunger Games tough - guy characters, give the tributes from 'baby bliss' traits like extreme naivete or an over - the - top positive attitude that is unique to the 'baby bliss' concept.
Create a really engaging setting. Describe the quarry in great detail, add some new locations or elements that weren't in the game. Maybe there's a hidden cave with strange markings or an old abandoned shack with a mysterious history. This will draw readers in.
Develop unique and complex characters. Don't just rely on the existing ones from the series. Create new side characters with their own backstories and motives that interact in interesting ways with the main characters.
Finally, interact with the Apathytale community. Share your ideas and drafts with other fans. They can give you feedback and inspiration. Maybe there are aspects of Apathytale that you overlooked, and they can point them out. Plus, when you engage with the community, more people are likely to be interested in reading your fanfic once it's complete.
Add a touch of mystery. For example, introduce a strange object or event in the Animaniacs' world that they have to figure out. It could be a mysterious song that has strange powers or a locked box that no one can open. By adding this element of mystery, you'll keep readers hooked.
Use unique character voices. Really get into the heads of each character and make their dialogue and internal thoughts distinct. For example, Natalie's cynicism should come through clearly. Also, add some unexpected twists. Don't just follow the predictable survival storylines. Maybe have a character make a completely uncharacteristic decision that changes the whole dynamic of the group.
