Mahtan Aulendil, father of Nerdanel.
I know about the beard, but it is so hard for to imagine (and draw!) an elf with a beard, so I decided to portray him in his youth.
"He usually wore a band of copper about his head. His hair was not as dark or black as was that of most of the Noldor, but brown, and had glints of coppery-red in it." (c) The Shibboleth of Feanor, HoME vol.12
