Now that the character's head is ready, you can move on to the body. You can do a simple rigging where all the body parts are independent of each other, or create some parenting between some of the layers. Refer to Creating a Hierarchy to learn how to parent your layers.
Simple rigging consists of leaving the layers in the Timeline view without doing any kind of parenting. Later on, you will attach those layers to a master peg and organize them in the correct order.
