How does this sound????

Fanfiction's a hobby that you can enjoy on the side, but the thing is, most people don't enjoy reading about OCs (original characters) - or at least, a massive amount of them like you're planning to write here - and they ESPECIALLY don't like self-inserts, placing yourself in the world of your book. Unless you can write your story AMAZINGLY well (you still probably won't get a lot of readers), you're most likely going to get flamed in the reviews.
