I would agree that they make little sense as a comparison. Liberty Square to Frontierland is intentionally subtle and elegantly executed, and there is thoughtful placemaking relative to the Rivers of America. The ability to take everything in simultaneously and have it look cohesive was a conscious choice. Tomorrowland to Fantasyland, on the other hand, is an obvious stylistic transition but a bit clumsy and abrupt without 20k Leagues.
World Nature (and Discovery, for that matter) is problematic because, from certain approaches, there is really no transition at all. It’s neither deft nor clumsy; it’s just nonexistent. I’m still a bit baffled that they’re not trying to pull Imagination into Nature. Without doing so, you end up with weird things like the World Nature bathrooms existing within World Celebration.
