I felt the island itself looked a little bit too small. I thought it was bigger in the books.
shareseems about right to me, but I remember in the books it had a small town or something at the bottom which it doesn't seem to here.
shareI’m not sure anymore, but as far as I remember, there were some villages on the island, too (in the books).
However, I don’t think they were ever mentioned in the TV show so I guess that this is one of the changes they did.
We've only really seen the beach, Stannis' map room, bedchambers, and dungeon, until 7x01.
Now we finally see a good length of the castle, the external walls, the long road up to the keep, and the actual throne room itself. We still don't see the rest of the island though, it's not as small as people think. There were resources here to keep islanders fed and enough room for a good chunk of Stannis' 100,000 man army at the midpoint of Season 2.
