Riverrun, Harrenhal, Qarth, Dragonstone and maybe Storm's End would be my guesses.

You're definitely among the best of the autotune video people.

How long does it take to make one video? It seems like it's a lot of work I would be way too lazy to do, even if I knew how.

Also, do you do anything else (like school or something) or is Youtube your full time job?
