I really like it too. I think one way they could improve the top is to increase the height of the arches as they get closer to the edges to produce more of a back-to-back, dual Hollywood Bowl band shell effect. It would make the top more dynamic, and make some of that cross bracing more visible from more vantage points. The cross bracing at the top is one of the coolest elements to the crown, and it would be a waste to only be visible from directly above.
But overall, I really like this one.
