I have made another thread, located
here that has the "check lists" of a good novel. I won't go into specifics, but here are some generals:
Use correct homophones.
Stick with characters you will enjoy for a while.
Make a plot you can stick with.
Make a story that you will enjoy for a while. If you get bored easily, it won't be very easy for you to write a novel.
Post yours!
