For Monsters and Dragons most of the things in the land get taller towards the back. For Nintendo and Potter they start off quite large right behind the portals, so kind of a mixed bag?
Very curious to see how hard they go on landscaping around the portals to hide the areas from view. Like Dragons is supposed to have a hillscape around it’s portal to block views into the land, almost like a berm, for example.
At very least you won’t be able to see in the closer you get to them. Across the hub may be like a Diagon Alley situation where you can see the Gringotts dragon across the lagoon.
