This is a very good effort, there are some scenes where you can't tell the difference.
Software used :
3dsmax, V-ray, Forest pro, Growfx, Mari, Marvelous, Frost MX, Phoenix fd, Nuke, Ps, Zbrush, Quixel
I could still tell it wasn't real by the foliage it didn't blend with the surroundings and how the water moved too fast and too smooth. But impressive though, I love things like this.
The inside shots are very convincing idd.
It's the outside shots that still look very cg and plasticy.
It's like everything that was originally manmade can also be easily made look convincing with cg. Like cars, machines, furniture etc.
Then comes natural landscape which is harder to do. After that humans and animals which even the best CG still can't do perfectly.
