Just got a question. What about the other Vala?? Where's Mandos and Yavanna?? Because they are of greater power then Lorien. If I'm correct, Yavanna is the second highest Valier, is she not? And Aulė, Ulmo and Mandos were of all greater power then Tulkas.
As for Hobbit, I think they deserve a place higher then Goblin's. After all, Bullroarer did invent a game after knocking off the head of a goblin.
I also think that they should be in between Orc and Dwarf because of their feats, even if they were few.
I believe that Ungoliant deserves a place higher up. After all, she did almost kill Morgoth.
I can't think of anything else other than the remianig Valar (Vana, Nessa, etc.) and they all do deserve a high place. They are Valar.
Oh, wait!! I've just remembered a few Maiar. Eonwe, Osse and Uinen all deserve a place in there for being a few of the Maiar named.
Wow, that's a lot!! Well, take what you want. After all, it is your list.
