You're light years ahead of me. My courthouse is still sitting alone on a big green square plot of land. I'm totally blocked how to arrange it with City Hall. I like the way you did that in yours!
Anyone who saw the interior of my house would realize the irony in ME giving design advice. But here are a few teensy things that I can think of. For what it's worth ...
Its gorgeous.
I would move the rabbit hedges backward, in the direction of the courthouse. The straight alignment of the fountains, the rabbits and the statue (and their equal distance from each other all the way across) makes it seem that none of the items is a focal point. I would also put something along the edges where the grass beneath a building comes up against the concrete surface/ pavementg of the patio area. Maybe some shrubs, or a fence or hedge ... A hedge would keep it looking formal and crisp. Or shrubs would make it less formal. Or even maybe a row. Of those tall slender trees that are in pink pots. That would look formal ...
Btw, just wondering ... Do you have gazebos at all four corners? Only two corners show, and I'm just curious, because I'm always finding myself doing mirror images on my stuff. Sometimes I wish I could do the spontaneous stuff others come up with, but then other times I just accept that I must have some Classical Greek ancestors who imbued in me a love for symmetry :)
