Cool only any concept that comes with her?
she seems familiar for some reason.
Other than that, if you like her face currently you don't got to try this but higher cheek bones will help with the skull thin type of look she got going on now.
^Unless you want her to look rugged, also i doubt it matters if your hiding her eyes behind the face mask.
I tried that method above before i went with my zsphere "way" of doing things and for me it seemed about the same, i did wing it and mess it up entirely though and didn't follow whatever guide there is for that method. 
Was it quick for you to do? being new to it? i am curious about a rough estimate.
