Jeor Mormont is actually Pycelle, but they're both pretty similar. Good job! The rest are correct!
Hurm, lemme me see if I can stroke my memory, here:
Row 1: Ned Stark, Catelyn Stark, Robb Stark, Jon Snow( "you know nuthin', John Sneww..")
Row 2: Sansa Stark, Aria Stark, Bran Stark(with Hodor), Rickon Stark
Row 3: Robert Barratheon, Cersei Lannister, Jaime Lanniser, King Bitch-ass, err..uh..I mean, Prince Joffrey
Row 4: Peter "Little Finger" Baelish, Tyrion Lannister, Varys, Jeor Mormont?(the Knight watch elder guy)
Row 5: Tywin Lannister, Margeary Tyrell, Daenerys Targaryen(dragon lady), Kal Drogo(medievil Conan)
Row 6: Lady Brynne(the big lady body guard), Ygritte(Jon Sneeww..), Theon Greyjoy, The Dog
Row 7: Davos Seaworth, Stannis Barratheon, Melisandre(witch lady), Gendry
...how's my aim? (good pixels btw)
My first thought was "how the hell am i meant to recognise them?"
But theyre quite recognisable, lol. Would be a bit harder if each row wasn't related. Still can't name a few/forgot names.
By using the description of the book I'd say that the fourth character on the third row is Geoffrey. Wheres my cookie? I'm guessing that the second last character is Milisandra.
I feel like the person who sprited this sucks at Cards Against Humanity...
