The eyes only deformed a little but I imported a second model including the eyes to see where I needed to pull out the bottom lids to correct the poke-through. For that reason, my next import had the eyes, just to make it easier for me the second time around.

As for correcting the jawline deformation, it would have been impossible to do that in Poser because the amount of morphing I did with the face wrecked the alignment of the jaw so when I had the character smile or open her mouth, it was a huge mess. I'm starting again because of the mess, so I'm going to try and limit the amount of deformation around the jawline and mouth so this doesn't happen again.

I looked for both Zbrush specific and I looked for character creation in general. A lot of what I found wasn't relevant or there were dead links - the vast majority of information I could find took me to dead links - so that's why I tried to focus the searches for Zbrush and get more specific with my pipeline.
