LEGO Metropolis

This is grand scale and majesty in a tiny package. Builder Klaus ツ uses nearly all white in the micro scale city, with excellent effect. The limited use of trans light blue adds a great contrast and splash of color without being distracting. The construction is fairly strait forward and not very complex, but the detail level is perfect. It's simplistic enough to imply scale, and complex enough to be very visually interesting.

Octan Corporate Headquarters

It would seem even the world of Micropolis isn't immune to the encroachment of corporate greet and dominance. This corporate headquarters by Steebles is brilliant. Even at such a small scale the building seems imposing and impersonal. The use of the crates as paneled walls is inspired, and the balance of details vs broad strokes is perfect.
