Hey Dartanbeck ,
Here is my rig aligned with the Man model but not attached. I have an issue with the left hand’s IK Target helper as i get flipped , somehow when I duplicate the rlight arm skeleton to the left side it messes up the IK chain or something. I have bones for the eyes/jaw and a couple for the chest area which helps when moving the arms etc. Hope this helps
I just updated the file , here is the new link..
