Thanks for the quick replies!
I started using Hash back in 2000, but I haven't really touched it since 2005 (been doing 2d and comp work). Now I've got a couple projects I want to finish; this is an original model and will be the first one I've ever given a full rig with constraints, dynamics, and smartskins. (Here's some of my older work in Hash; pretty basic rigs involved.)
Oddly enough, almost the entire head had its normals facing inward! That helped a bit.
Found a decent angle to start pushing out some straight lines; one other question. Is the 5 point in the 2nd picture going to cause problems when I start doing a facial rig?
edit: wow, adjusting the gamma is actually helping quite a bit.
