Nice AU58 coin a true slider IMO vertical shadow down the center of the profile while still retaining full luster. But I am usually very pessimistic on the first cup in the morning.
To the OP: 1) That Walker is beautiful and don't let anyone tell you otherwise. 2) I wouldn't feel comfortable grading it, as there are more experienced people around here that can do so. Doug is very knowledgeable. 3) What I look for when I go looking for a decent walker (and I only have 1 to date.) is I look at the drape lines on her dress (which is actually the red and white stripes on Old Glory.), her cap, and the feathering on he eagle. I also look at her breast plate, cap, sandals, and the stars above her outstretched hand. However, those are my personal preferences. IMO, the Liberty Walking is a very beautiful coin at XF grades and better, but once it really starts to wear down you are left with just a silhouette of what was once true art. It is sad to see a very worn Walker, however that just means that it did it's job, and did it well.
