Hi and welcome to OSM,

You say in your changeset that your source is Bing aerial imagery and nothing else, yet you map buildings that are only visible in Google - WHICH IS ABSOLUTELY FORBIDDEN. Were there other sources such as on-the-ground surveying?
The shape is poor of the Torre Zembra. It looks perfectly square for which there is an ID Editor function in the right click menu. I've square the building but you still need to clarify the source of these building additions.

Also you say your edit is in/around Villamagna, but you too changed the Corso Mazzine in Vasto from Secondary to Tertiary. By what measure is that change correct? Why this in the same edit? 

Please let me know.
