I sincerely think LEGO Architecture is a brilliant concept for both as a theme and for MOCs. I would like to see some more global representation within the theme, as most of the Architecture sets have been of American landmarks, and it would most certainly be nice to see the line go more global (I personally would like to see some Asian and more European landmarks done). I am not too fond of the skyscrapers such as the Empire State Building or the Sears Tower. This is not to discredit the sheer wonderment of these buildings, but because I don't think they're particularly fascinating to render in LEGO at the scale it was designed in. Aside from the high quality packaging and a novelty printed tile, they pretty much can be built even with bricks from a small collection. I believe it would have been more appropriate to render those buildings at a larger scale, although I would imagine that the price would skyrocket as a result. My current favorite, which likely won't change, remains the Fallingwater replica. Architecturally it is a beautiful building, and despite LEGO elements being geometric, I feel that the organic nature of the building was rendered quite beautifully at the scale it was designed in. The value of the set as a parts pack is also unquestionable, but frankly I adore the set too much to have the heart and will to take it apart!
