I really like how you draw them, you're so good with a quill! The detail of the hand before the characters and the way you do the shadows... amazing!
Quite original how you've done Arya's face and hair, I like it!
Sandor Clegane looks a little too old maybe, considering he is supposed to be 28 years old when he's with Arya. But he looks so impressive, I wouldn't dream of cross him!
