The ground seems extremely flat, Streets could use some lowering where the most wear would have happened, like wagons, walking, and rain have pushed it lower into the soil, If you have a look at a paved street even today you can see that it's not flat at all.
IMO the foggy/mostly melted snow atmosphere/lighting looked better. Very nice city coming along, hope to see it finished! Regardless that snow material could use some work; it's very flat. Some sparkles and subsurface scattering and other shader magic could do wonders for it EG https://www.youtube.com/watch?v=pSuWH910028
