Some corrections area in "notmyproblem". Your Mapbox Satellite imagery seems poorly aligned, the builing was oversized. Added a tree row while there.
Not good in a self intersection area, the grass. Proper is to map the outline of the grass areas, map the inner space line then select both outer and inner lines holding the shift key and create a multipolygon which is real easy in ID Editor (It's right click to open the pop-up menu and hit the plus(+) option.
