These are Caphalor and Enoila, two characters from 'Die Legenden der Albae - Gerechter Zorn' (don't really know how to translate this...) by Markus Heitz, although Caphalor also appears in 'Die Zwerge' (The Dwarfs) by the same author.
They are Albae (some kind of dark elfs), but in this book they are the good ones, what makes it very interesting.
By the way, their eyes are supposed to be black, and Enoila is supposed to have light strands in her hair. Actually, she has four of them, one for each of her children.
I'm sorry for the lines on the paper... this was meant to be a quick doodle, but it turned out to be something more, and I still didn't find out how to remove those lines. Every tip I found on dA was presuming that your lines are blue, and was just removing this colour, but mine are grey. So the lines are still here.
I drew this with a mechanical pencil.
