As per request, a Mama Murphy that doesn't look like a "60 year old crackhead", and hopefully doesn't look like "a 60 year old crackhead with plastic surgery".                     
The goal was to have a middle aged but weathered Mama Murphy, hope I delivered.             
Will use this page to upload any future Mama Murphy edits as well. 

Options(So far):
Subtle Mama Murphy: "just a few years younger and slightly strung out from the chems without looking god-awful."
