I think, that if it is on a human body shown for beauty or visual effect it should be an unaltered image. A little touch up here, and a little touch up there is lying to the potential viewer. Lets face it, you wouldn't buy a VW Golf with RX7 doors would you ? Filters, or obvious alterations (like legs for arms or colour changes like a purple face for example) can be cool. But editing out body imperfections and enhancing beast sizes/more vulgar areas to be more pleasing to the eye should be left true. Just my opinion, might help.
