When I first looked at this wonderful MOC by LEGO 7 I thought it was an official set, and that got me wondering, what made me think that? Is it the building style? The photography? I realize that even years after looking at LEGO creations every day I still don't totally understand the intangible, specific nuances that make an official set look like an official set. What do you think?
