This footprint is valid, though it should be squared. Press q arter tagging to square the corners of rectilinear features. I modified this footprint and uploaded it using Changeset: 158481640 for you to have as a reference. There is a zoom sweet spot in imagery where one pixel in imagery is mapped onto one pixel on your screen. Using this sweet spot helped me to determine the building's shape. 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/
