The HDR does allow one to see the building, but I am not sure this doesn't reduce the impact of the lights. I would like to see a non-HDR image with more emphasis on the lights and less on the tree and paths. For a first attempt at HDR it is good, although I personally do not like the dayglo sky. A well composed and shot picture with good structure detail on the trees and path.
It is a beauty. All around I have to say well done. The sky gave me a real "wow" moment when I viewed it full size, but I would like to see what it would be like with a little more natural look to it. The court house and grounds look magnificent!
