I'd agree with Esther on the forehead...

Displacement is surely not dynamic enough, at least in Poser, to accomplish facial expressions... I don't think?

By the way, I just went and blooming well properly skinted myself buying zbrush, largely inspired by this thread.

Been drooling over it for a while... then I finally went to download a trial last night, for a looksie... and it was no longer available on trial download!

So just bit the bullet and max'd my card. Oh well... in the long term it should be a saving ;-)

Now I've got to try to learn how to use it... hmmm...

...and I bet they now reduce the price. LOL. No really, if they do, I'll cry...
