Ok, it's doesn't look like a ultra-res screenshot from a cry engine game, but this looks great. (except for the scene with the windturbines, which actually looks pretty bad. (The trees at that screenshot and the green/brown-ish texture on the ground doesn't seem to be right.). However, the other screenshots are beautifull.
"It's more like a bunch of trees"
It isn't called Uningine Forest. Unigine Valley is the name.
