I deliberately thickened up her eyebrows, nose and chin a little, to illustrate this quote :

"While still in early youth Fëanor wedded Nerdanel, a maiden of the Noldor; at which many wondered, for she was not among the fairest of her people. But she was strong, and free of mind, and filled with the desire of knowledge.
-  Morgoth’s Ring, HoME Vol 10, Part 3, Section 2, Of Fëanor and the Unchaining of Melkor "

So she could be more conventionally pretty though I'm not sure about her lips, and as usual the photography has done the painting no favours..  I did this because I thought the hair might be more educational to paint than last week's hairy dog, and I do feel I learned a fair bit from painting it.

... I amended her eye and mouth to give better perspective.  You can see how hard it is to be consistent when taking photos when the light changes!
