They would need to be creative and be good with details. I'm big on details so it's my opinion, but they do need details and a good story line that would make sense. They'd need to be good with spelling and grammar and all that fun stuff. Hope this helped a little but!!
I think in order to write well you need to put your feelings into your story. Right from your heart and put a lot of details into your story to make it more detailed and interesting. use different points of view and make your characters developed and make them have feelings so that when people read they can see what the character is going through or at least get a sneak peek.
