Hello Andrea.  We welcome you as a new mapper.
I noticed that you started to map one of the most difficult tasks there is on this project.
However, Most of the buildings are tall buildings which need to be mapped on a special way.
Unfortunately, I see you did your best, but it is unfortunately not mapped correctly.  It is also not a task for beginners. Even experienced mappers will have trouble with this.
Please select a more simple task to start with.
Best regards and keep mapping
