*whispers* I have a massively overinflated sense of my own self-importance and have always slightly identified with Galadriel (!). I think it's to do with hers being a story about choosing to use one's powers for good. I don't identify with any other Elves at all (it's only the stories of Men in The Silmarillion that really interest me). But something about Galadriel's story has always moved me at some very deep level. I think it's that "gesture of rejection and denial".

And Eowyn's story is deeply human, you are quite right.
