Here is a MOC I've entered (or tried to) into the Brick Fanatics CMF Series 9 Diorama Building Contest. I actually have a slight overhang over the 16x16 plate size so will need to alter it to actually enter the competition oops. This is slightly disappointing as I've already made several compromises to my original vision - lets be honest, this crappy CMF sword is not Excalibur - I really wanted to use a Brickarms Claymore.
But for now here is the current layout which was very much inspired by Aubrey Beardlsey's illustration from Sir Thomas Malory's Le morte D'Arthur...
