Hello. Great work mapping all these details! Few suggestions for improving the map details:

1. After tracing the building outline based on the roof shape, it is a good idea to move the way slightly, so that it aligns with the base of the building: https://wiki.openstreetmap.org/wiki/Roof_modelling#Typical_errors_in_the_interpretation_of_roof_geometry_from_aerial_images

2. Multiple roads have a `layer=*` tag in this changeset. Unless the ways are physically below/above ground level, there is generally no need to add a `layer=*` tag. In case they are below/above ground level, it may be a good idea to include a `tunnel=yes` or `bridge=yes` tag on the road. If it happens that the road is covered but not physically below ground, use `covered=yes` instead.

3. Since the roads are internal to a private complex and are behind a `barrier`, it may be a good idea to include an `access=*` tag, such as `access=permissive`

Happy Mapping!
