"There are nasty trollers who say things just to be mean. That aside I would love helpful hints. I would love to be able to say Honesty what I see that could help a picture. If I do a fantasy Picture, where the background is just as important as the figure, I don't think it's helpful to say where are the shadows? Sometimes, a picture does not need shadows." Turtle wrote. I notice stuff like lack of shadows, and, don't like it. If you are working in 3d it should be 3d all over. But, I no longer comment on anything where I would say it is less than perfect. I have been accused of trolling when I commented that reflections weren't right, and hair was a bit flat looking. I think most folks don't want critiques, actually. At least in the Poser gallery. But, that's just my opinion.
