@Minyassa: The opinions you described in your OP are probably less biased than the answers you get here - in a Poser forum...

I agree with the gallery owner, you mentioned in another posting, who said the difference is if you created the models and textures yourself. Everything else is posing and staging where the software rendering does most of what finally comes out as an image. To compare it with photography: It's not art when you set up a scenery in a studio and find the best lights for it. A photographer not only combines that he also knows his tool and what he shoots is what he sees in the preview, but no 3d software preview shows the image as it is in the render. A lot of Poser users barely know their tool and their renders show it. Not everything which is inspiring or creative to us is art. Judging the galleries probably 10 % do really artful images, in my opinion. By the way: you know that art critics are generally hated by artists? Film critics are hated by all involved in film making AND the audience. Nevertheless I trust some film critics more than my best friends if I decided which film I want to see because they have a professional eye on what they see. The Poser forum is the most unlikely place where I would expect a honest critic that could help me if I were out making art.
