First of, it's night. Now, I know that the prev. screeshot fearured dusk, but now we know for sure that there is day/night and that it's still in the game. I'm sure that features come and go all the time right now, so we can never be too sure that something featured on a screenshot now will be in the game.
Secondly, it seems like we can stop worrying about the size of the buildings compared to the units. Yes, this is probably one of the largest buildings in the game, but I still think that the size of the door etc will be approx the same on other buildings.
Third; ES likes to show off their water. Fourth; Those trees look amazing!
Fifth; It's a bit hard to see, especially for those who like me have the sun shining in on their screen, but there are cliffs between the building and the sea. Those who have complained about AoK's cliffs can be happy, cause ES have answeared your prayers! These cliffs looks amazing!
