Traditional Animation - 1 Character drawn on Multiple Layers?

Hi,

I would like to use Traditional Animation and draw a character running.

Would you draw the entire character (head, body, arms and legs) all in one layer? Or would you draw the head on one layer, the body on another layer, the arms and legs on their own individual layers?

I understand in Puppet Animation, yes, you separate your character elements into layers. Wondering if you would do the same in traditional animation.

Thanks,
B
