Looks interesting. You should change the ground color frim outside from green to something grey to avoid the green bounce light into the window. And be sure to set quality to ultra, then it should look even more similiar.
I have the problem of not enough GI sampling some times too … I wished we could adjust different aspects of quality - noise, GI sampling, bounce depth, … . Here in this case the GI looks to splotchy.
(UI Example: at Rhino there is a simple custom mesh quality slider for dummies. And if some one like he can enable detailed options and set detailed parameters. Same could be added for the Enscape quality. I don’t like the single slider for a mix of different options. )
