Hi, thanks for adding to the map! One thing I noticed is that you're sometimes "gluing" areas to adjacent road ways. It's suggested to not do that and leave a gap for a variety of reasons, such as that it's not that accurate, and makes future editing more difficult. (see https://wiki.openstreetmap.org/wiki/Editing_Standards_and_Conventions#Areas_and_Ways_Sharing_Nodes) I get how it might seem "right" at first, though! Happy mapping!
