Female Bust WIP

I've been doing more Zbrush practice. Here is a female bust that I've been working on. I plan to get a low-poly version into Maya with UVs.
Added eyes and softened the cheekbones: I didn't like the proportions, so I rounded out the face and shortened the neck. I also refined areas like the mouth, nose and eyes. I also added more detail to the hair:
I used Polypaint to add texture (the shader is the flat-lit "chalk"). I forgot the eyebrows so I roughed them in using Photoshop:
Next, I intend to fix the holes in the hair and to add differences in material properties using specularity and glossiness for the eyes and lips.
