That's a gorgeous shot, David. If it were to dolly/track down the stairs it would be even better, but I'm thinking that that would be hard to tripleshoot.
Interesting note: in Monty Python's Life Of Brian, in the scene where there are thousands of people watching a preacher on a rock, and the characters are in the cheap seats way in the back ("Blessed are the what? The cheesemakers?"), note that, separating the characters from the preacher is a small valley that the crowd disappears into and rises up the other side. Our mind fills in the hundreds of people not seen. So, creative shots like that work, too.
Also, a number of people in a smallish area looks like more people than the same amount of people in a large area.
