A couple of minor bugbears (apart from Sheeran's appearance that is) in that episode I had were Euron Greyjoy's outfit and a very minor, but noticable change in Dragonstone, which I will get to in a bit. So, that outfit. A bit too hip, brash and trendy for the setting, no? I mean, he looked like he's a member of a modern rock band or something. It just clashed with the usually impeccable costume designs we're used to seeing on the show. I mean, he was wearing skinny leather trousers with a taper on them for fuck sake.
Then there was the very small visual change Stannis' war room in Dragonrock. Did someone sneak in there when it was abandoned and recarve the dragon on the wall? It's a very different design to the previous, realistic-looking archeological aesthetic of the previous seasons, which I didn't think needed changing at all, as it looked much better.
