While the auto mask works well and there are tools to fine tune a custom mask, I do wish there was a brush within the plugin you could use to quickly eliminate areas from the mask, such as hair and fabrics.
For example, I would reduce the effect of Portraiture 3's adjustments on the subject's lips and around the eyes slightly. By outputting the results as its own layer, it's easy to selectively apply the mask to the image. Before (left) and after (right) of the automatic skin mask and adjustments being applied.
