I used to be a huge fan of starwars books. You should expand on it- develop your characters and maybe detail the conflict more so that we can put
ourselves into the story kind of, you know? (also if Ham Sola is supposed to be Han Solo, I am almost certain that you won't be sued as long as you
don't attempt to sell this work, so you could go with the real names if you felt so inclined.
Keep it up
