Hi, you identified and mapped some buildings accurately here, however others inappropriately share nodes with others, have not been appropriately shaped or envelope multiple buildings visible in imagery. I flagged some footprints here I think could be better mapped. 

Check https://osmcha.org/changesets/171747971 for an example. 

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/
