Thanks, guys! I''m completely smitten with her.
DollyKim: The knee joint in the tail is just reverse what the upper thigh/hip is. I took some pics to help show what I mean.

The whole breakdown of the tail.

Side view of the bent position.

Her bum. The groove faces back at the knee and is as deep as the one on her upper thigh/hip, so it bends to a 90 degree angle.

Another exposed shot. It has no grooves to bend forward, the string is resting on the resin, so it's difficult to get her to hold the tail in a forward bend. The last few joints don't have any grooves, so most of the posing is in the upper leg. The tail fin has a special ball and socket joint so it can flip and trun.

Hope that helps.
