IF: You do great work & I like you imagine the characters from a work such as A Song of Fire & Ice by Martin.
I recently read a novel, The Teutonic Knights' by Henryk Sienkiewicz. I think you would find some inspirational ideas therein. The protagonist, Zbyszko of Bogdaniec, his uncle Maćko of Bogdaniec & especially, Kuno von Liechtenstein, the villainous Teutonic Knight. As I read the book I envisioned the characters & wondered how someone with your talent would portray them.
I once got in a vicious argument with a guy saying that Clegane was pure evil. I argued he wasn't. As it turned out the other guy was talking about Gregor and I was talking about Sandor. this is why we don't call character by their surname.
