I'm gonna focus on the negatives. Some of the line work is really sloppy here and there. Lips, neck, hair, eyes; the really dark ones especially. I suppose the dark ones on the hair could be used for some sort of layered effect, but at least have them smooth. On the goggles and parts of the armour, the lack of texture or something makes them really stand out. The goggles look like a sketch next to the realistic value of the face.
Everything else looks fine, though. I really dig the values on her face and armour. Alse the scratchy texture on the armour here and there.
