If you'd like to see what the masks looked like for this: here you go.
The script worked well, nothing overly complicated. The held breast did require shrinking the center size (one of the sliders) down to 75 though. There was a bit of redrawing on this, so it's not like I plopped it into the script and it all worked magically.
I did come up with another feature working on this that will get incorporated into future versions as a checkbox: "Avoid Blur"
