Welcome to OSM! You spotted buildings in imagery, but many of the footpritns you mapped here envelope either multiple buildings or entire plots. 

Each footprint should represent one building. Use shadows and colours and plots to discriminate between adjacent buildings. 

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/
