For those who’ve always wondered a bit what the series might have looked like at various stages during conceptualization of the people and places, Kimberley Pope—a concept artist who’s worked on Scott Pilgrim vs. the World, Agora, Elizabeth: the Golden Age, and of course Game of Thrones—has shared a number of examples of concept art, both for this season and last. There’s some spoilers in the season 2 material, rather mild… but there’s also a lot of amazing material, including various iterations of the Dragonstone and Harrenhal designs, good looks at the Eyrie with a kind of cable car (instead of a winch cage), and more.
Very much worth a gander.
