Nice pose; makes me think she ponders the challenges that await her.
Sorry for some poor English thar in the prior question. What I mean is, weighing the skin; giving it the appearance that gravity has taken a hold of a youthful and elastic face. The tools I was experimenting with to try this were:
-Clay (hotkey BCL [sometimes I forget the name of the brush but remember the hotkeys to get it]) with lazymouse @ 1 with intensity under 15, with rounded edge alpha.
-Others have proclaimed using Blob (hkey B) with low intensity and a bumpy or rounded edge alpha
-Sometimes, Buildup (h key BCB) with rounded alpha, lazy step 0.01, super low intensity.
This is just to make skin look thicker in some areas, and to show the weight of the skin. You have achieved this pretty well in the face, curious if you wanted to reveal your technique and insight.
