Post 7: Stuck on Hug, Blocking New Project

So while working hug I ran into an issue. I had no idea how to go about parenting the parent and child together (pun somewhat intended). I did some research and couldn't find any tutorials or examples of people parenting rigs together. The closest I got was parenting two rigs to the same object or parenting two hands to the same object.

I decided to take a break from the hug project and start a new animation. Originally I planned to do the game animation one, but I knew that would take a lot of planning and research. I wanted to start animating right away so I decided to reference a dance.

Current Block

Spline of first 8 Poses

This is a spline of the first 8 poses. I'm not in spline yet! I just wanted to see how it looked at the time.

SPLINE ISSUES:
-I feel like the first pose transitions into the second pose too fast. This is how it is in my reference, but that's because my first pose is a quick transition during the actual dance.
-I made the mistake of moving the shoulders after I moved the arms. This causes the arms to move a bit wonky. It wiggles around while moving.
-The foot on the left also rotates a bit weird when sliding into place. I used two controllers to rotate the foot and it looked fine blocked, but I probably need another pose or two for that foot. That or go into graph editor and move keys around.
