Tony - they are such beautiful buildings, but the detail has been lost - they appear to be slightly overexposed ? I was only working with your small jpg version, but the amount of detail that is still there in the shots is amazing - only a quick play and obviously been a little heavy handed with my approach (edit - ok, REALLY heavy handed lol) - but have another look at them, and see if you can bring out some more of that hidden detail - will really help with these images
