how did you attach the head to the body?

I followed Yamato's TentenV3 head-transplant tutorial at Poser Penthouse, with some slight adjustments to account for the different figures I used.

The hardest part was reconstructing the joint parameters for the posable whiskers and ears.

The most tedious part was modeling a new upper-neck part (and the back of the skull) to fill in the gap, and then UV-mapping it so it would take the MilCat textures.
