Unconventional roofs on medieval buildings

The Jester's Prestige
The latest MOC from Luke Watkins Hutchinson a.k.a Derfel Cadarn made me spechless. This medieval diorama is surely one of the best I have ever seen. The textures of the buildings are amazing. And the roofs of the buildings are not like the ones you normally do yourself. These oblique roofs are the sign of a new age in historical themed building. Seeing the participants so far, It looks like the Classic Castle Contest this year will be quite impressive.,
