Everyone always watches Arwen in this scene but me, I prefer to watch Elrond. The look on his face and the tears in his eyes always gets to me. The War is won, Middle Earth is safe, and his daughter is alive, but he still loses. He wants Arwen's happiness but in order for that to happen he has to let her go. She's going to marry Aragorn and he's going to sail to the Undying Lands and they will never see each other again. This is a bittersweet moment for Elrond, and it shows.
