The Western footprint is too large. You can draw the building footprint area ~95% of the roof size initially, so that you have a margin for any change of shape that occurs when you square the footprint. The orientation of the Eastern building is inaccurate. There is a sweet spot of zoom where 1 pixel of the imagery maps onto 1 pixel of your screen. This will allow you to better determine the shape and orientation of buildings, because it is effectively the highest resolution image you can see. Thank you for your contribution.
