The mesh behaved very well in zbrush for the quick morphs I did, but I need to try something a little more detailed to really get a feel for it -- like maybe the spandex morph I mentioned.  Here is a closer look at the head morph. This was just a quick few minutes work. (I made the body a little more hourglass also -- and added some booty :)   ).   Oh, and congratulations on the release of Antonia -- she's a beautiful figure.
