The hills in the background in these screenshots really remind me of the desert hills in Mario games, especially SM64. But the big thing that pops put at me... what's up with that Rant model? It looks really weird.
Also, thank you for accommodating the GPub bugs. It's nice to see that the upper ring is not actually rounded and is just clipped manually; rounded surfaces that can be wallwalked on cause the viewpoint to flip, such as the ceiling of the bottom half of mid on nano and the ceiling on Karith outside the front door of alien default.
