This is a very impressive MOC. I think you have done a brilliant job in capturing a specific sense of place and environment–everything feels consistent on a thematic level. The amount of detailing, and scale of the overall composition is just right, I think that LEGO as a medium performs best when a certain amount of restraint is applied. The window design on the middle story of the main structure is absolutely fantastic.
I'm not really feeling these pieces in the courtyard though:
They might be placed too deliberately to sucessfully create the impression of naturally occurring variations in the ground material.
Will we get to see some pics of the reverse side? It also appears as though the main structure has a removable roof. Does this mean that an interior is in the works?
