Tulkas and his wife Nessa from the Silmarillion. Nessa is Orome's sister, so I wanted to make the two somewhat similar, even though the Valar can technically look however they want.
I've always enjoyed seeing pics of the Vala and their spouses together. I enjoy seeing the similarities and the contrasts.
Hope you plan to do Namo and Vaire as well. (Hint Hint! )
Ahh I love your lineart!
