no, not to worry, re-opening them and commenting is the peer review to help you be the best mapper ever.
first of all, the building needs to be added.
someone added more buildings years ago, but not this one.
i believe a comment i made nearby months ago implies there is good mapbox aerial imagery in this area.
second, add an address, name, and anything more you can.
i don't know what type of amenity might fit best.
that is it! you could also add further nearby houses and buildings for more details and fill out the map some more.
