You need to work on your story structure.
Your story has too much of 'he said' included in it. Every other sentence is 'he said'.....You need to include more descriptions, like 'He then looked up at the sky, took a deep breath, and enjoyed the fresh, clean air he was inhaling, as the wind blew a warm breeze across his face'. Describe what they are doing, the surroundings, stuff like that. You make it too much like a script-type, where it is mostly just lines the characters are saying. You have to get the readers to picture what is happening in the story, not just have talking. When people read the description I gave above, they can picture the person doing that, or even feel like they are the main character doing that. When you just have 'he said', you can't picture much except the characters just standing there, doing nothing but talking.
Also, reading a bunch of words together is harder to read. You need to break it up into paragraphs and include proper spacing.
