Comment on Daru Shadowplay Twi'lek by Giolon
Now that there's the 3-option system, perhaps, but there's a difference between groping and covering.
Relaxed hands cover, but that's usually done with the forearm. Curled fingers are more of groping. *nod* Even so, if there's an image of the arm covering, it still should be marked mature if the character/person in the picture is naked.
