Yeah, thanks PaganEagle... the Move brush does seem to be the one to go to first. Certainly for making more structural adjustments.

Also the Polish brush seems to be a better bet than Smooth... which actually I think was established earlier in this thread somewhere...

There's quite a learning curve to ZBrush, but I'm a few months in with it now! My goodness time flies!

So, starting to make some reasonable in-roads towards figuring, at least the core parts of it, out now...

Above is an early attempt I made at a Michelle morph...
