I’m a fan of the circular landside portion of the terminal on this one, though I was hoping that the airside portion would turn out to be a symmetrical W shape, rather than the slightly irregular W that it turned out to be.
It was pretty easy to draw; the only curves could be drawn with a circle cut out of another circle, and everything else was straight lines save for the tiny circular bump in the middle of the airside concourse.
