For example, I read a book where the word "chiseled" was used a bit too often on several pages to describe a man's features. There is a thing called a thesaurus. Use it. Repetitive words pull me away from being absorbed into the story. Change it up. Besides, if you have a weak vocabulary, this is a good way to strengthen it.
Now, my rant doesn't just pertain to words, but scenes as well. If you are going to describe a common scene that you know appears more than once in your story, change the description. Don't keep saying "the crackling hearth was ablaze" EVERY time you mention a fireplace. Be creative and figure out different ways to describe a roaring fire. You can Google your question on a particular feature you are trying to describe and something will come up. I am not privy to a specific website that will do this. Yet, I know they are out there.
Not much else today. Keep writing and do not be afraid to express your thoughts the way you see it. Who knows, your voice may be the next big thing.
