In 2019, New Orleans replaced their old terminal (the lighter silhouette above) with a new terminal (the darker silhouette above). Since the old terminal was still present, I decided to draw both.
The new terminal is essentially almost all smooth curves, which was a pain to draw, but looked nice when it was done.
The old terminal, on the other hand, has a lot of straight lines at mostly right angles. However, the tip of the D gates turned out to be a regular heptagon (seven-sided shape), which is pretty unique—I don’t recall any other airport terminals that incorporate that shape!
