Puppet with multiple facial and body profiles with movement and rigging issues

Hi everybody! I’m new to character animator and have been working on creating a puppet with 5 facial profiles (LP, LQ, Frontal, RQ, RP) and 3 body profiles (LP, Frontal, RP) in illustrator. When I had my character rigged with less behaviors, things were working well, but as I’ve added a couple of new behaviors (walk, motion library & breathe) along with the LP & RP body profiles, some things aren’t working anymore and I’ve noticed a couple of other quirks with the character. Any help or suggestions to fix these issues or improve the character are much appreciated, thanks!

Issues:

• Head is flying off of the body
• When head turns, shoulders and arms are moving
• Having Issues with walking behavior
• Having issues with motion library
• Eyebrows are barely moving at all only on Left Profile. I have full expression in all of the other 4 facial profiles.
• A couple of “rigging issues” present on the puppet that I can’t get to the bottom of
• I’d like both arms in the frontal body view to be in front of the head, is there a better way to accomplish this than how the layering is currently set up?
