@Acer2020: a bit too much symmetry, even for man-made stuff. Yes, man-made structures/areas tend to be at least somewhat symmetrical, but not usually 100%. In your maps, even the flowers at the bottom of the second one are symmetrical. Again, while symmetry, to an extent, is a thing in man-made stuff, it often can work against you in tile-mapping because if not done right it makes it too obvious everything is on a grid.
Also, the wall in the second image, it might just be me but this seems to cause a perspective problem. One, not using a wall-top tile, since we're outside and there is no ceiling overhead. Two, the top of your wall is even with the floor behind it, but it's just black, and there is no railing or anything. If it is supposed to also be a wall for the upper section, it would need to be taller.
