Hair is usually one of the giveaways. I see that especially with the long side strands in the top image. Other than that, the eyes are amazing and really sell the image. If I didn't know I was looking at CG, I wouldn't go looking for hints, I'd think it was a photo.

I think some of the criticisms here are made because we're looking for things to criticize. E.g. the notion that the skin tone is wrong in image 1. As if there were such a thing as "east asian skin." There are a huge variety of skin tones in east Asia, as everywhere else. Besides, when looking at a photo, you never know exactly what has happened to tones, anyway.

I think the second image is far better than a lot of folks seem to credit it. I'll agree that the texture of the forehead and upper part of the nose is unnatural, and the nostril area is a bit too pristine, but otherwise, I buy it.

The Polaroid.. sorry, it took me several looks to perceive that she is supposed to be sitting/leaning on that chair. The face is believable, but the placement and shadowing are not, and wherever the body has bare skin, especially the lower torso, well, it's just not there. Still, if I were flipping through a bunch of images and not focusing, I might think it was a photo, and that's more than I can say for my own work (and most folks here, let's be honest). :)

The Defontaine images are awesome. Other than the hair, I have a bit of doubt about the wrinkles (wish I could do that well myself, mind)... there's something just a bit too "clean" about them.
