Ah yes Gwynn. memories of my first DSLR wedding shoot (my wife's cousin got married there a few years ago). An iconic building, nicely captured Sir.
Could I offer a little constructive comment?
If you reduce the Radius and / or Strength in your HDR software, the white halo effect will be reduced.
Also, a tweak of Lens Correction (made manually) can eliminate / redcue teh converging verticals and the feel of the building falling backwards. If oyu expand the Canvas beyond it's original size, you'll reduce the risk of losing thte extremities of the building prior to cropping.
Hope this helps. But gotta say, you've had some great shots from your visit to Leeds.
Best regards, Brian.
