Imho, you've got a bit too much space between the eye (usually, there's one eye distance between the two eyes), which gives her more an animal look than a human look, imvho. That feeling is reinforced by the lack of nose or mouth. 2DKnight's edit imho fixes the issue.
There's a readability issue with dark hair + dark skin, too, especially since your brown skin is somewhat blue-ish. I'm impressed how the hairband fixed that, clearly separating the two clusters. Clever trick.
