/3/ - 3DCG

i have a floating character which consists of his rotund body and two disembodied hands (pic related). it's my first time rigging a character, is the way i've drawn the rig on the right correct, since all the rigs i've seen in tutorials and images have a bone through the middle of the body (in my case the head)? the way i've thought it is that i don't want any deformation of the head but i need a root bone for walk and idle animations
