For that first one, are those walls supposed to be slanty, or is that 3-point perspective?
2-point perspectives have no 3rd point( or should I say the 3rd perspective is infinitely far away) so straight walls should be parallel to each other, and perpendicular to the "ground". If you just Google "2 point perspective", you can see that the buildings' walls are straight up and down, and parallel to each other.
Perhaps it's just me?
Keep up the good work~
