Reading Do Tolkien's Elves have pointy ears? got me thinking:
Elrond and Elros were born Peredhil, and given the choice whether to belong to the Eldar or the Edain.
In choosing, does their physical appearance change accordingly? In other words: did Elros or Arwen keep their pointy ears?
Or are Peredhil an exception and don't have pointy ears in the first place? (which would make all depictions of Elrond and Arwen I have ever seen faulty.)
