After Marilyn Monroe was dressed for going out and finished with her makeup, she'd study herself in a full length mirror, then turn her back and glance back at herself. Whatever element of her makeup jumped out at her, she'd make less noticeable. She'd do this until she had a complete look.
I've always thought this story is an excellent metaphor for writing genre fiction. Anything like overwriting, fancy words, and moments of being too clever need to be toned down.
That doesn't mean that a viewpoint character can't be clever or use an occasional big word if it fits his personality, but it should be the viewpoint character, not the author.
During the rewriting process, be sure to look for things that stand out too much and remove them so the story is what is important, not your writing.
