X-posting out of laziness, thought you'd enjoy the link : If the end-result, the pic, is a good one, who cares how it was made (speaking as someone who started in 2D on paper waaaaaay back) ? And as to nude pics - have you ever checked out just how many bathing Susannahs, rising Venuses, and abducted and dragon-guarded maidens there are in the history of art ? Just one example : http://www.ibiblio.org/wm/paint/auth/altdorfer/loth-daughters.jpg Albrecht Altdorfer : Lot and his daughters, 1537 mural in a bishop's palace (!)
