The hair length of Khal Drogo is about right according to what "A Game of Thrones" describes, but the hair isn't braided as it is in the book, and it doesn't have bells. These are really important because in Dothraki culture whenever a man wins a battle, he adds a bell to his braid, and whenever he loses a battle, he cuts off his entire braid in shame, according to "A Game of Thrones." The book said that Khal Drogo has never cut his braid, meaning he has never lost a battle.
