I LOVE THIS! That's exactly how she should look like. It's amazing what you did with her face, it looks so calm, bright, strong, and it even reveals that she is clever, she just needs to mature in her thoughts.
Yes, maybe that will affect her mind to be stronger later in the book. I'm currently reading clash of king, and even after Ned's death, she wants to be a good little girl/bird. She subjects to Cercei's will, and she can't see what an evil that woman is. I just can't understand Sansa, but this picture makes her awesome.
