Thank you! We're glad that people like it. The scale of the castle went through several iterations in the planning phase - our main concern was to get the proportions right between the sloping top half and the rest (actually we designed it from top to bottom); the one we finally chose made it possible for the micro shuttle to be included (well, its way larger compared to the landing pad than in the movie; but still, it's there).
The booklet is a recent addition; last place we exhibited the castle, we weren't sure if ppl were familiar with the movie or not, so I threw together the booklet: it has the same text as the UCS sticker; a few concept arts, WIPs, and behind the scenes from the movie; several movie stills and last but not least a side-by-side comparison of the movie stills with the corresponding details from the MOC (it beat having the scene play on loop from youtube on a tablet).
