You have no plot yet O_o Start thinking about it. There is a book written for the NaNoWriMo which helps you preparing. My friend has it and I read it. They say you should make a list with the things you like to read about and the things you don't like to read. It can be anything: the type of character, the way it's written (first person ect), what time, what place, historical or not. After doing that you see what you want to write about and you might get an idea.

Arwen is cool, but I like her better in the book.
Aragron and Legolas are a cute pairing indeed XD

Viggo is much more of a ranger. Never washing his hair since he meets the Hobbits until he becomes King XD All dirty when he is fighting. But yeah, Fuji could never be a ranger. Tezuka is a better one.
