Whilst I was watching the last installment (being very pleased that I had enough self control not to watch them ALL at once...) I did some sketches of the characters.
Drawing from the television is more enjoyable than I thought it would be - moving figures allow you to examine the characters from all sides and through a variety of expressions. Ultimately you get a better drawing as you are forced to capture the essence of the character rather than get hung up on the details.
Now I just need to find something else to get addicted to!
