With a little postwork you could make the hair look more realistic if you want to, but on the other hand, I like this hair the way it is. The eyes are too dark, but this is the texture, not your fault. I did not like her eyebrows - they are much to high above her eyes and I reworked this part of the texture. Besides that this texture is great. But back to your image: I like the expression on her face -she looks as if she is deep in thoughts or is daydreaming. I would save this face to the library - it's wonderful.
