When writing your story, make sure it is well spelled and try not to use 'said' or 'say' Like if a character is yelling, they 'howled' or 'shouted.' Also, make sure your story has a lot of feeling, which means just add adjectives. Don't use common words, for example, instead of 'red' use 'crimson.' There's a bunch of websites that could help with this. Make sure your story is one of a kind, and try to not fall into the pit of fanfiction clichés. Anyways, hope this kinda helped (:
