I too am experimenting with the Zbrush Hair and it's coming along, you just need to experiment with all of the option dials.

I would also confirm it is easier to model your figure with the mouth half-way open and the eyelids at half-mast and the rig/create morphs to open and close them from there, works for me.

Your figure looks very kwel ED, well done.

Comitted to excellence through art.
