So, this is only the smallest critique compared to huge strides you've made in overhauling the game's look (I'm really excited to see what it looks like when you're done with it), but it seems a bit strange to me that apartment doors would be transparent, as that would leave the occupants without privacy. I could certainly see it as an optional feature (the upper city is home to the obscenely wealthy, after all), but logically, people would want privacy, especially if they were paying out the nose to live there.
The door does look fantastic, I just felt the need to bring this up from an in-universe perspective, as that could be immersion-breaking for some people.
