That one is a lot better, but still looks off enough that I didn't even approach the uncanny valley. It looks great but it doesn't look real.

In the other video the foliage looks horrible. Come to think of it, I doubt I've ever seen good 3D foliage, let alone examples that come close to real.

the pebbles on the ground looks quite real. But the larger boulders in the background is too textured and not enough bumpiness and also too uniformly flat. That's what seems to make it fake. also the water looks great, but too uniform and perfect. Real water has lots of little flaws and it's usually not as clear too (things like muddy water is hard to render i guess).
