Originality is dead.
I know. This sucks to hear and maybe it’s been beaten over your head a million times, but that just proves my point.
Every idea has been done, in some shape or form.
The key is to realize that every idea can come in a million flavors.
It’s up to you to figure out that profile.
This isn’t so much an exercise as it is a reminder.
You’ve built your characters from the ground up. That makes them original. That makes them yours.
That being said, it never hurts to read more books and watch more movies/television to prove it to yourself… and study.
