This is the biggest castle I have made so far, The only reason I made is for a school project called "Escape from Kraznir" I love school projects that let you build with lego, well here it is "Castle of Krill"
Thats a good idea. Just use a lot of bricks to make sub-levels to the castle. I hope LEGO gets this idea and uses it on their next Castle series. It might help put an end to those rather silly raised baseplates.
