Lost in this World: Rewrite Plans

Now that I have finished my short chapter story, Lost in this World, I have copied and pasted it into Microsoft Word. Without breaks in the chapters, it was about 21 pages long which is a little disappointing. I plan to rewrite and edit the entire short story, so I would like some advice, tips, etc. Here are some simple questions that would help me make the story better. Thanks for the help!

  • What did you like?
  • What didn’t you like?
  • What did you understand clearly?
  • What didn’t you understand?
  • What needs more work?
  • What needs more detail?
  • Should I introduce that Shep is a dog at the beginning of the story?
