Creating a good exposition for narrative writing

Last week, we have started looking at how to make a really good narrative. First, we learned how to make a good opening. One technique that I learned is "show don't tell". This means you are describing the thing but not really saying what it is. An example is " The lake shimmered from far away". Next, we had to make an interesting setting. This includes the place and time where all the things are happening. Here is paragraph I wrote that shows the setting.

Old ruins were the only buildings I could see. Tumbleweeds were all around the place rolling like a bowling ball. The wind was humid. It was dry and hardly any rain. The windows were all shut and most roofs are rusted. It feels like I’m the only person here but at night I hear the dragging of their foot across the sandy gravel.

After that, we know learned what characters are. There are two types of characters, a protagonist, and an antagonist. Today, we are now looking at the narrative arc. This is the body of the story.

If you have any tips on how to make a good narrative story, please tell me.
