When I saw this amazing vertical city by Sebastian Bachórzewski, my first thought was, “What a neat microscale building,” followed almost immediately by “HOLY crap! That is minifig scale.” To say that there was a lot going on here would be an understatement. Between the many residential and commercial units piled high, to the floating vehicles coming and going at various levels, to the street scenes along all four sides of the base, this Favela is home to many faded, bitten, random, unwanted and surplus LEGO elements, cobbled together in some surprising ways.
In this scene from the top of the stack, there are assorted stickers which look to be from Star Wars vehicles, along with brick-built graffiti, several car tires, and this large trans-orange container from the Hero Factory theme.
This scene from the base is one of my favorites, showing many nefarious individuals, and a stream of murky liquid flowing from that building on the left. And check out the roof towards the top, made from this tread part.
