Thanks for suggestions.
Snow is a mix of some procedurals and hand painted maps connected to displacement. I used a converted snow material from evermotion tree and tweaked it a bit.
Good point, I didn't take my time on materials. I started this project in vray and converted everything to corona. I was in a rush so I decided to focus on the enviroment and let go everything else.
With the ligtning this is almost what I wanted to achieve. It was meant to be late evening during snow storm, so it should be evenly lit mostly by the sky and artificial lights. I wanted to avoid diferent shading on facades. As for an evening scene it is also overbright, but exact photorealism was not my goal. Sky was found fast and it quite suits me. But I heard similar opinions that I could improve it :) The light from the sun is an error which i missed and forgot to correct ;)
Best regards.
