Mouth and nose are in the right position. The eyes are a little bit higher but to me it looks better. I changed the mask, too. It is wider but not as big as the original. Because if I'll do it like this it seems too big in contrast to her head.
That mask is going to look pretty darn cool. My only comment on the face is that it maybe a bit wide in the front. Id double check how wide the face is around the orbital socket. In the side profile view you may want to pull the face back a bit. The area on either side of the nose is usually just a combination of the cheek…
