Hello and welcome to OSM.
I saw you wanted a review.

From a technical point of view, your edit is good.  I mean, you drew some shapes and added "building=yes" to them, so they will show up as buildings on the map, and that is exactly what is to be expacted.

This one seems a bit strange, though:

If I look at available aerial imagery, I don’t immediately see a building here, or maybe it’s a much smaller building.  My comment is solely based on what I see on Bing and Esri imagery.  If you have local knowledge and are sure that a large building has been built here, then it is fine.

Have a nice day.
