I see I'm a bit late to the party.
Not to quote anyone in particular, but just remember that publicly released concept art is supposed to evoke an emotion or feeling. It's not an accurate, to-scale rendering of the land. If you fly a plane over Disneyland and take a picture from that same exact spot once SWL is completed, I can guarantee you that what you'd see will look very different from that art.
I'd say the biggest difference is that you'd see show buildings. There's no reason to be concerned over the size of show buildings from this because most concept art intentionally doesn't show (or deemphasizes) them. In fact, since there are no real noticeable differences from both pieces of concept art, and we can't see inside of the buildings, I'd say it gives us nothing to worry about. Unlike TSL's newer art.
I just hope that most things we're unable to see haven't been (and won't be) cut.
