Hello, Welcome to OpenStreetMap!  It is great to have you as part of our community of map aficionados.  Thanks for your edit to the map.  You cited Google Earth as one of your sources, unfortunately, we are not allowed to use Google Earth when editing OpenStreetMap due to Google's Terms of Use.  To protect you, the OpenStreetMap project, and users of OpenStreetMap data, the edit will be reverted. You can redo the edit using only sources that are allowed.  One very good source for trails is the Strava Global Heatmap (requires an account, but the account is free).  You can also use Bing aerial imagery and Esri World Imagery.  You can also collect a GPS track using your phone or smartwatch.

Some minor additional things, the trail should be connected to the nearby road (presuming one can walk from the road to the trail).  This is helpful for routing.  The trail should *not* be connected to the powerline.  highway=path, rather than highway=footway, is probably more appropriate and matches the other trails in the area.
