This is a hard choice, because all pictures were amazing!
But at the end, I voted for sgtgrandpa
The whole picture represents evolution very well, and it's one of the best photomanipulation I've ever seen.
I'm still a proponent of the idea of separating 3D content creation from 3D manipulation (Main subject is Poser generated or other pre-fabricated 3D stock meshes integrated with a scene.) It's just not a good thing to have all of the stuff competing in the same contests and things as if were the same process...it's like having a competition between illustration and photography. Having mentioned all of that I like Freddy 3D to win the contest, because of the quality of his final image and the clever use of evolution as a theme.
