Breathtaking Improvements in Talia (Patreon)

I've been looking more closely at how the ribcage expands (or has the potential to expand) when breathing deeply.  In the past I made breathing a simple linear transition between two shapes.  But as you can see above the sternum moves out, and then up as you breathe more deeply.  I've also learned that bodybuilders can exercise their diaphragm to more dramatically expand their ribcage.  It seems to be a more old-school form of bodybuilder posing.

This will be interesting to rig.  It's not something I've seen before in FBB animations. :)
