If you think your setting is too similar to one of the random genres, you can chose to not be selected for that particular one. He said something about that earlier... unless I'm mistaken. Then again, things can always be more distopian.
Fairy Tale / Medieval covers a wide range of styles and settings-- from high fantasy to historical medieval to a Disney-esque fairy tale. If one of those seems too much like it, you could always do a different one.
Then again, I chose to not be selected for fairy/tale medieval for my fantasy comic, so it is an option if you feel it would be better that way.
