2 step!
My middle position is on frame 10 – before frame 10 the head turns right (character view) and higher then ten it turns left.
I have set up one grease pencil object for the head and one for the body but also one for each eyebrow since I wanted them to be easier reachable for animating.

when you are done add a armature to the scene by adding a bone.
Go into edit mode with the armature and make a basic setup
start with a root bone in the 0,0,0 of your character, then for simplification we start with the neck bones and the head
they should be parented in that order
not parented you add another bone that will be ctrl for your pictures – how to set this up is coming in a bit
