Thank you so much for your feedback and analysis.
This is the current direction, but I'm not 100% sure on the skin tone...
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.
