Hi Owl...  Why?  because other mappers want to know what you are working on.  Thanks for adding the buildings and parking.  The buildings could be shaped better.  Tip, press the Q key when the item is selected and it will square up the corners.   
The parking you added is not a space, but should be amenity=parking  and maybe parking=surface.   If you have any q's ask, or there's a discord, a slack, and a community site at  https://community.openstreetmap.org/
