The castle layout was made by me (Mockingbird), Michel and Marakoeschtra. The castle in the middle was made by Michel. The layout on the left of the castle was mine, and on the right is Marakoeschtra's. Together we had about 4.5 m castle layout. It looked really good.
PS. Sorry for the poor quality of my photos
. Better pictures will probably soon be available on brickshelf.
