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.
You can get story ideas by observing your daily life. Simple things like a conversation you overheard or a strange event you witnessed could inspire a story.
One way to get story templates is to check out online writing communities or forums. Sometimes, fellow writers share their templates there. Also, some books on writing techniques might have templates included.
