Need help finishing off a walking strawberry - rigging not quite right but no issues showing.

I am animating a logo for an upcoming video, and I've taken it so far, now I am hoping you guys can help me figure out the final "what am I doing wrong" parts of the rigging 🙂

When the character walks the legs and the majority of his body look great, buthe left hand holding the guitar neck, and the guitar neck, and moving wierdly.

I don't know how to fix this, and any help would be gratefully received!

It's my first post, it wouldn't let me attach my AI file so instead I attached a screenshot of the rigging and result, hope that is the correct procedure.
