Hi Andrew, Good job improving the accuracy of the two buildings in the SE and including the entirety of the building under construction in the NE (rather than just the roof. All building footprints you added here represent buildings visible in imagery however, the imagery allows them to be mapped more accurately; typically they are oversized or their shape should be more complex. See how I mapped some buildings you added here https://osmcha.org/changesets/171381560

It's much easier to map anything more complex than an L shaped building in JOSM, so mapping them with just a rectangle using ID is okay. I generally consider footprints that are equal to or smaller than the roof to be accurately sized.

When mapping buildings, please trace the shape accurately. Accurate building footpritns aid population estimates and prevent issues like data overlaps. Zoom in so that you can see the outline of the building and mark the corners carefully. Exclude shadows and yards when tracing the footprint. Keep in mind that you are looking at the roofs of buildings, but mapping their footprints. Depending on how the scene is lit, pitched roofs may have light and dark sections that belong to one building. Generally pitched roofs overhang the walls of a building, so a footprint slightly smaller than the roof is accurate. You can scale selected features in ID with shift+(-/+), or JOSM with ctrl.+alt+Lclick & drag.  Take care to make contributions that others can build upon.

Please keep this feedback in mind when contributing in future.
