I'm planning to write some short stories about a space ship captain and his crew mates. I got the idea from a TV-show named Firefly and few science fiction movies, like Blade Runner and Star Wars (original trilogy). My biggest concern is that I don't feel my work has much originality. The world has this great government from Earth, which wants to take control all over the colonies and planets, rebelled colonists forming an alliance (which lost the conflict "Colony War"), no aliens. I think my work just seems too much copying and too little real innovation. What do you do when you have to face the problems with originality? Should I erase my plans from my laptop or refine it more and more?
