The footprints you're adding are valid, appropriately squared, and fairly accurate, though sometimes slightly oversized. You mapped with bing imagery which is older at time of mapping and so the footprints do not align with ESRI. I recomment offsetting imagery before mapping. You can read about how to do this in my project comments.

The 5 Southern most footprints here are fairly accurate though should be squared (q). In the North you deleted and replace footprints with lower quality ones. Deletion is sometimes the best option, but not always. Here the buildings could have been moved (m) to align them with ESRI imagery rather than mapping from scratch (provided they were accurate). Please keep this feedback in mind when contributing in future. Thank you for your contribution.

Valid footprints but the imagery allows for them to be more accurate. Pease remember to square them with q. Please keep this feedback in mind when contributing in future.

Vakid and quite accurate footprint. Please remember to square footprints when appropriate.

I think the northern footprint envelopes multiple buildings.

Though the imagery allows them to be mapped more accurately all the round footprints you added here are valid i.e. they represent round buildings in the imagery.

Welcome to OSM! These footprints do represent buildings in the imagery but they could be more accurate. Remember to square footprtins when appropriate.

The footprints I flagged here have odd and inaccurate shaped. check to see if a building's footprint could be accurately mapped using simple shapes before considering more unique options.

You correctly identified that this is a T shaped building

You correctly identified buildings in the imagery here but the footprints could be more accurate. I flagged two footprints which I though were well mapped. It looks like you mapped using alternate imagery or an offset leading to a missalignment with ESRI. I corrected this.

A valid and appropriately shaped footprint. If it were a little smaller it'd be excellent. Keep in mind that pitched roofs tend to overhang building walls somewhat. Thank you for your contribution.

These footpritns are valid and you distinguished between round and square buildings well but they could be more accurate. Take care to make contributions that others can build upon. please remember to square (q) your footprints. The southern most footprint should be extended southward; it is partially covered by a tree but its full extent can be determined using bing.

The Eastern footprint represents a building while the western one represents a likely garden. Beware that walls can cast shadows similar to buildings; use context clues to help you determine which is which.

Published using OSMCha: https://osmcha.org/changesets/168403109

The western footprint is oversized, the southern one is a garden not a building and the eastern one is actually square not round; you can tell becasue of the roof colour. Buildings with blue roofs in this area do not tend to be round. Determine how the scene is lit and use that information to aid your interpretation.

You were doing the right thing by modifying the residential area and improved its geometry, but it and a highway share nodes with buildings. Hold alt while mapping to prevent this.
