The concave edge reveals are exactly as the video represented in terms of size and scale. Trying to hold the finished product - seen from the street in who knows what weather and light - to the standard of a CGI created environment is a bit naive.
The construction of those 'simple' reveals added immense engineering and constructability factors to this building and I have no doubt they passed under several budgetary carving knives unscathed; a miracle in this age of cost-cutting.
The windows are also fairly representative of what is shown in the promo images and video. They're not at all the bait and switch we often get in designs like this. The architect's concept was realized in terms of the houses or favela in the sky idea. Period. The building should already be added to the architectural tours of the city.
