hi, hm, why did you map a a like a whole center of the city as a commercial area? it's not all office centers, read more about this type here - https://wiki.openstreetmap.org/wiki/Tag:landuse=commercial

will change some of them where there are obviously just living houses - to residential because thats definitely more suitable. If there are some areas where commercial zone is suitable, can be mapped separately, but mapping is like that is just straight incorrect
