Here's a fun link to the Fantasy Novelist's Exam. Basically, it's a list of questions about your fantasy novel. If you answer "yes" to any of the questions, the teacher will give you an "F" and suggests you should abandon your novel.
The list is a joke. It mentions many of the overused tropes in the fantasy genre (Is your main character a young farmhand with mysterious parentage?) (Is the evil supreme badguy secretly the father of your main character?) (Is your main character the heir to the throne but doesn't know it?)
However, I have written a fantasy novel or two or three that I would have to answer "Yes" to a few of the questions.
Is this the first book in a planned trilogy? (Yep - Woman of Honor is book I in a trilogy)
Do any of your main characters have apostrophes or dashes in their names? (Trolls do in Knight of Glory and Champion of Valor - there are new races that I explore in Champion of Valor and made sure there weren't any more apostrophes or dashes in them.)
Does your novel contain orcs, elves, dwarves, or halflings? (Orcs - no but they are mentioned. Elves - well, Drow are. Dwarves - yep. Halfings - no.)
All in all, it's a funny list. What tropes are you sick of seeing in fantasy? What ones don't you mind? Do you think elves are better than dwarves?
