This collaborative build, by Grant Davis and Eli Wilsea, was definitely a crowd-pleaser at BrickCon last month. It was packed with all sorts of interesting detail, minifig “life” and cool construction techniques. It took home a trophy for Best Medieval Building as well. The rugged technique they used on the battlements (the bits on top of castle walls) was one of my favorite details and the motorized waterfall was ingenious!
