Hi you identified buildings in the imagery here but they are square; not round. Round buildings cast a rounded shadow not straight lines. See how I mapped them here https://osmcha.org/changesets/169536083 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/
