An omnitional movement of the head
The fact that we can move our head in all direction may had a lot of realism in all spar, trick, parkour and MAS !!

We can already kind of do this. Rotate chest and relax pecs or counter-rotate pecs.

Yeah but that may make the tori off balanced
I was more thinking about some arrows that make the little boy able to turn the head 90° on the side.

After all of these years, I guess he'll finally see his shoulders :3

This isn't a horrible idea, but I'd prefer if it was part of a script / mod, because the idea is basically useless other than for making sparring replays look better.
