Low Poly Modular 3D City with Day & Night Textures

3d modelling of modular city blocks with Daytime and Nighttime textures. Downtown areas and Suburban areas. Different types of tall skyscrapers and also shorter & smaller buildings. Maybe 30-40 skyscrapers and 20-30 buildings. Cinema 4D format is prefered, or FBX and OBJs as long as textures are provided separately. Please only apply if you can show me examples of previous similar work (architecture, city models etc) This is a big project so I will only hire you if you can show me a good portfolio with relevant work.
