[OSM-legal-talk] Attribution/Licensing for map derived from Standard OSM TIles

1) That text is fine. Please link to https://www.openstreetmap.org/copyright
2) It sounds like all you did was personal styling, as your actual
improvements to the area were made in iD, so I would say no, it's not
a Derivative Database and there's no share-alike obligation.
