Thank you so much for your feedback!
@wilbertvandenbroek Thank you! We are very happy that you liked our work. Thats true, the railing is missing, because it's hidden behind suspended ceiling, but appartently it's not so visible since there is no lighting coming from the top.
@husherson2 Thanks! Brick texture is from Poliigon library, a little bit tweaked by us ;) To light up the exterior scene we used HDRI maps and low sun to make warm feeling in the render. In the interior we used just Sky + Sun :) Hope it explained a little bit :)
