Is this those two cliffs in builder with the waterfall and river? If so, they look REALLY cool

If not, good luck with new project, sounds like an inventive idea!
Edit: Just realised that this was something you haven't made yet but are planning to make :S Even so, those mountain/cliff things in builder are still awesome
