A lot of people draw him completely without a nose so when I read the book and it's said that only half of it was cut off I'm like: Oooh! and then Well, what on earth is that supposed to look like?! So yeah, I think you did a brilliant job drawing that and now I can better visualize Tyrion! :3 I also love Tyrion and Penny together. They're like a mirror of Jaime and Brienne's relationship. Older, jaded, and generally beaten down man meets & befriends a younger, more innocent woman who annoys the man with their idealism and naivety. Perhaps Penny will be able to bring out the better side of Tyrion like Brienne managed to with Jaime.
