I think that you've gone a little overboard with the circular buildings you added and have actually mapped some linear buildings as circles. Zooming out can help you to identify building shape and orientation becasue you can view what is effectively a higher resolution image.--- I believe that the circular footpritns you added have been copy pasted. Doing this is useful and saves effort when appropriate. However please take care to modify the footprint afterwards as necessary e.g. rotate and scale so that the footprints you contribute are accurate. In this case a good number of circular footprints appear to be too large--- I encourage you to attend a mapping event; you can find them here https://osmcal.org/ the missing maps mapathons offer live training.
