Well, getting better at fiction writing involves paying attention to details and description. It's also important to study different writing styles and experiment with your own. And always revise and edit your work to make it the best it can be.
Joining a writing club at school or in the community is a great way. There, they can get feedback from their peers, participate in writing challenges and learn different writing styles from others.
First off, you need to have a clear concept for your novel. Think about the genre, the themes you want to explore, and the message you want to convey. Develop interesting characters that readers can relate to or find fascinating. Outline the main events and conflicts that will drive the story forward. Also, pay attention to the pacing - keep it engaging without being too rushed or too slow.
