In books like The Hobbit, and Game of Thrones, they have a map at the beginning showing the world. I want a map like this so that my story has more of an image-able world.
That's because it would be confusing to readers otherwise. Also, these are made
before they commence writing, because it's common knowledge among fantasy authors that if you don't write to a map, you'll never be able to make sense of the result enough to make one later. Try making a simple one at first, that shows where everything is, but may not be as detailed as the ones in published novels.
Also, I'm not usually a fan of the first-person narrative style. There are one or two authors who can, IMO, pull it off well (Conan Doyle, John Marsden in the Tomorrow series) and they're always in the style of a journal or diary.
Also, I'd recommend against publishing your first efforts. Trust me from experience, it's always shit. Refine your skills before you release anything. That said, It's nice to see you're trying your hand at writing, and fantasy at that, a genre that requires a thick plotline and a rich world to pull off. Also, have you read Robert Jordan's The Wheel of Time series? If not, I strongly encourage you to pick up The Eye of the World at your local bookstore. I can also pretty much guarantee that by the time you're ready to read the final book (Book 14) it'll be finished.
(But mostly by Brian Sanderson, because Robert Jordan is deceased. Sanderson's been doing a good job in his stead, though)
