Hi! Since you requested a review, I looked over your changes here. Nice job on all the details here! Most everything looks great to me as far as tagging goes. The only issue I see is with the multipolygons. A really common mistake is to tag both the member ways (the outlines of features) *and* the multipolygon relation. Really only one of those options should have tags such as building=school or whatever. In this case, I'd say the best way would be to just remove the school building multipolygon, since I wouldn't consider all those shapes to be parts of one building - instead they are each their own building structure, if that makes sense.
