LOL. Sorry, this story came to mind with your idea. On [another forum] someone innocently posted a photo once on a CG thread without stating it was a photo although the message text eluded that it indeed was a photo- herein enters the part where a couple people thought it was a CG pic trying to be 'photo-real' and basically commented that it wasn't true to real-life. But it wasn't really their fault since it never blatently stated the photo was a photo; however, lifes lesson number 106,532: There will always be critics. And number 106,534: Even reality can be unreal.
As for posting the models I've seen models that in their model state are basically nothing, but; with image maps, general textures and lighting applied along with grain to match what the model is being composited on you see the final image and take 4 looks at the model in amazement realizing how much texutre and light play a part. The prize should be the entire scene.
Anyways, interesting idea. You first- me not anytime soon(I suck).
