Really nice render. This spot seems a little bit too dry for rhinos though. I would add quite a bit of grass and other green stuff to give the rhino some turf. I really like the tree next to the camera. It catches the spirit of rhino safari really well since standing that close to a rhino (this is inside its personal zone) requires a quick escape to a tree in 0.0 sec flat if the beast decides to feel annoyed by your presence.
