Now that I'm back from work, and I can look at these pictures on something bigger than my tiny phone, my thoughts and speculations
1. Aerith's church: I mean, it's very pretty, but I can't comment on it since of all the Midgar locations, this is the one we've probably seen the most of in an unaltered form. It's appeared in Advent Children and Crisis Core as a staple landmark. It's always truck me how much natural light Sector 6 seems able to get compared to Sector 7. I'm very curious about the finalized geography of Midgar
2. ShinRa Office: Okay, I'm gonna address the elephant in the room: That is President ShinRa Sr there, and he's gone from a mauve suit to a black/blue suit...All he needs is a red or orange tie and well....ahem anyways.
That low joke aside, the thing about this office that strikes me is zooming in, you can see what looks like monitors on either side of the room.
The one on the right doesn't look familiar...but the one on the left looks a shade too much like another part of Midgar we've seen.

Could just be my eyes desperately trying to make sense of it. It's an absurdly small detail to put into hand-drawn concept art...unless they REALLY want to go big with just how much power ShinRa Inc has if it's own president takes the time to spy on the day to day events of his citizens.
The monitors behind the desk are another detail from the game. Only a few side-angle shots show it but he does have four monitors.

3. Sector 6 highway: Holy...moly. That's tiny little Cloud right there on the left. There's gonna be some at least low-level platforming going on in this game. On the left side you can side some worn out pavement writing with an arrow pointing up.
Since neither the robot hand or the crane are in their original locations, I'd be inclined to guess that the cityscape we see is the Sector 5 slum town. If the art means they're trying that hard to be accurate to the original game's aesthetic, we would HAVE to see the sector 6 park too, and it's nowhere to be seen. It would make sense that as a mainly residential area, people would built ontop of each other to make the best out of the limited spaces in the slums that are relatively habitable, like the training hall in Sector 7.
But the biggest thing that strikes me about this, and what I had hoped would carry from the initial trailer is the sense of verticality. Everything is just so friggen BIG and full of detail.
