Hi, and welcome to OpenStreetMap! Since you requested a review, I looked over your changes here. Looks great to me, no complaints! Regarding geometry, one resource you might be interested in to improve the trail is Strava's heatmap. It is a little bit of a hassle to make an account and get the cookie info, but once you do it's an awesome source of data for improving trails and whatnot.

Anyway, let me know if you have any questions, and thanks for your contributions!
