I thought I'd share a little posing tip from Zombie-Antonia: you may have noticed that combinations of the shoulder z-rot (bend) and y-rot (swing) can produce ugly creases in the armpit region. That's something I found hard to avoid, even with JCMs, and I think it's basically another case of trying to do something with a mesh that your body can't do.

So here's a (usually) better way to pose the arms: user either bend or swing on the shoulders, and do the rest with the collars. That's why I tried to make the collars as mobile as possible in the latest version. Antonia's right shoulder (which as we all remember is Poserese for upper arm) is bent down and her right collar twisted backward. Her left shoulder is swung forward and her left collar twisted forward. I've then used the up-down motion on the collars to bring her shoulders back to a normal height.
