Nerdanel the Wise was arguably the greatest sculptor in the history of Tolkein's Middle-Earth. Her father was Mahtan who learned the working of stone and metal from Aulë, the God of Crafting, himself. Her husband was Fëanor, the maker of the Silmarils.
I can't say how much I love you for giving her decent muscles. Nerdanel is a brilliant character and you've depicted her with real strength and vitality.
