Hi, you appropriately moved the highway to prevent data overlaps and make the relative position of features more accurate. 

The vast majority of footprints here represent individual footprints, but two in the South with complex shapes envelope two buildings each; pay attentetion to shadows, roof colours, and access to buildings to know where one building ends and another begins.  

Good job modifying the existing building to make room for adding one visible in imagery, though the SW footprint is still longer than the building is in reality. 

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/
