Create a pencil drawing collage featuring the top 10 fighters from Game of Thrones. The collage should include Jon Snow, Arya Stark, Jaime Lannister, Sandor Clegane (The Hound), Gregor Clegane (The Mountain), Brienne of Tarth, Khal Drogo, Oberyn Martell (The Red Viper), Tormund Giantsbane, and Daario Naharis. Each character should be depicted in their iconic attire and in dynamic, action-oriented poses that capture their unique fighting styles. Ensure each character is unique and only appears once in the collage. The overall style should be realistic and detailed, with a cohesive composition that highlights the strength and individuality of each character.
