damn nice! good ! exellent!
can you say how time it takes you? for head?
i know nurbs is hard to model, but the resualts are great!
for me to model a head with polys is about 4-6 hours for the wrap model and after that 1-4 days for tuning (that can never end)
will appriciate any info you give
WELL DONE!! KEEP IT UP!

;;; I hope your doing well with the eyelashes:) 

your characters look very natural (not to mention the great likeliness of your actor faces)… just keep em coming. I have to clean my desk from the drool now, see you.
