Generally you appear to be identifying buildings in imagery thoguht you are not mapping them as accurately as possible. 

Beware that there is a difference between building footprints and residential areas which tend to envelope them. Check here for details of tags you do not understand https://wiki.openstreetmap.org/wiki/Map_features. Residential areas and buildings should not share common/grey nodes.

Please keep this feedback in mind when contributing in future. Thank you for your contribution. If you want to experience the OSM community or to get timely feedback from other mappers; I recommend that you attend a mapathon. You can find events here https://osmcal.org/
