Nomen est omen, as the Romans used to say. Let's see:
Celebrimbor: "Silver-fist". Silver -> a second place -> not worthy of winning.
Celebrían: "Silver queen". See above.
Tar-Míriel: Tar = high lady, queen. Mîr, Míre = jewel. This dazzling woman is the jewel of the show. She might be a diamond in the rough, her brilliance dimmed by her ever so horrible husband, but she has got a lot of potential in her (and a personal name compared to the Celeb-something-club), so let us now give her a chance to shine.
I trust that a voting decision that is based on languages that were so dear to Tolkien is Middle-earthian enough...
However, just in case:
++TAR-MÍRIEL
Because she would have deserved to be the fourth Ruling Queen of Númenor. Winning the Second Age Survivor may serve as a consolation prize.
