Like all architectural and engineering designs and creations It Is beautiful and a pleasure for the eyes. It's obvious that a 3D-printed or printed terminal or apron will be much more appealing than handmade ones. That said, I would have done it differently. Given the space, time, and money, I'd do something more imaginative (if fictional) or more distinctive, like Salzburg, Funchal (3D, of course), Skiathos, Corfu, Espargos, Punta Cana, etc., etc. But that's a matter of personal taste.
There are much more eye-catching realizations like Milan MXP Airport, Tortolì and Olbia "Costa Smeralda" airports in 1:500 scale realized some years ago by New Wings Models Group (Luca Granella & Co), Leonardo should remember about them, but i am not able to find their realizations.
Then i remember a spectacular Paris CDG diorama in 1:500 scale: realized in all details with plastic terminal buildings, a real masterpiece. It was presented during a competition in Wings900 many years ago, i remember Paris CDG was the winner, Leo was running with the beautiful Willy White Snowflake International Airport and i was running with Funchal 3D.
