Armatures and fish head tests

I've started making the armature for the mermaid sculpt puppet. Its pretty basic.

While i was waiting for things to dry (air drying clay on torso and pelvis) I started playing around making a fish head with a movable jaw. I have been thinking about it for so long and not doing anything about it- I'm the most procrastinating person in the world.

I'm going to take the card shapes as a template and make it in Sculpy light....
