i gotta say, Arya has always been my favorite - in the show and the books - her character is so powerful and resilient. All the best of the Stark traits and her own unique strength take her on one of the most interesting journeys in the story. This girl is AMAZING! I'd like to see a couple portraits of her as she grows and changes and goes through all her trials!
Her and Jon have the Stark look than the rest of their siblings. Ned's talk with her about Lyanna was one of the best because Arya though it was a joke because she was very beautiful, but after reading more about Lyanna I have a feeling Arya is in some way Lyanna Reborn.
Absolutely love the waay you portraied her! Gotta love Arya! Must say she looks like a young version of the Lyanna you drew (i always thought that when she grows up she will be beautiful just like her aunt)
