This isn't concept art. It's an officially-published visual render of the whole park, created towards the end of the park's construction, meant to be accurate to the final version of the park, so that Universal Creative can do digital flythroughs to figure out sightlines, attraction placement, guest flow, ETC. If you look back at actual concept art from 2019 or later, you will see differences (IE the cancelled Dark Universe theatre show, different building placements, ETC).
Disney does this exact same thing internally too, they just don't often publish it for marketing. We see their domed screens Imagineering uses for digital park flythroughs in Disney+'s The Imagineering Story. It's disingenuous to knock Disney and praise Universal as if they operate differently and one is somehow more competent than the other.
People forget concept art is supposed to be "concepts" of what a planned attraction could be like, and are not the final product, though I do share grievances at how some art reveals how budgets and lack of ambition can lead to worse products than promised.
I keep seeing *some* Epic fans misinformed about how the themed entertainment industry works and seemingly wilfully obtuse about themed entertainment criticism; I see a continued narrative perpetuated by people like Wallin Ballin on Twitter that somehow Epic Universe is gonna be a game-changing, world's best theme park. Don't get me wrong, Epic is gonna be *really good* and fun when it opens, but I don't see how by any conceivable metric that it's supposed to be artistically more impressive and grand in scale than legendary parks like the Efteling and Tokyo DisneySea.
