The vast majority of building footprints you digitised are accurate and valid. I flagged some which I don not think fit that description. You could use a suplimentary source such as bing and switch back and forth with (ctrl.+b) and/or zoom in and out to aid your interpretation. You propperly resolved a highway building overlap. 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.
