I'd have more contrast between the hair and the skin, maybe go extremely pale, but that's just personal taste for aestetic reasons.
And aesthetics are sadly out of my field of competence, so it's not so much a thought than it is a feeling.

If you want red skin the red highlight of the hair may be too much. Maybe try full black, or a different color for the highlight.
You could also try shades of pink or purple for the skin, although i have no idea how it would make her look like. I saw it here and there for succubi and other seductive demons, hence the advice, not sure it would fit your character though.
