Yes indeed. Kevin Hall is back. I was lucky enough to sit next to him (for about a hour) during 'Brickvention 2011', as well as talk to him about his new Castle MOC. I was indeed very impressed with his creation, as well as his 'reasoning' behind his MOC. Kevin builds like a true castle buidler would, it is very dynamic and organic, with most of the planning being in his head. He has a very deep understanding of how real castles are built and he puts this knowledge into practice. I can tell you that he uses both old and new Lego bricks in the same structure, and he doesn't sort any of his Lego into "old" and "new". it is sorted by colour AND size. The white bricks in his castle range from new "pristine" white to faded almost to "tan" in colour, but as the structure is very large this colour variation works perfectly.
Overall Kevin was fun to talk to, and his passion for Castles and Castle building has not diminished what-so-ever. So I am sure we will see more of his work very soon.
There are some more pics of his Castle in my flickr folder:http://www.flickr.com/photos/21313870@N05/sets/72157625834276156/with/5358442451/
