I must admit, there are many people who look suspiciously like their avatars
... in particular
Saucepan Man and
Estelyn. There are a few though...
Finwe: tallish, with long, shiny jet-black hair. She is very confident, both in the way she walks and dresses, and she looks just as good in jeans and a T-shirt as in stylish clothes. A rather sophisticated face, with dark eyes. The hair is what stands out most to me, I don't know why.
Nilpaurion Felagund: Tall, with spiked blonde hair. He has light blue eyes, or maybe green. For some reason it is very easy to imagine him with a surf board.
I agree with Fordim that Pio should have auburn hair.
More when I think of them...
