In short, I'd like to create it to test myself, but I'm having a devil of a time finding the right stuff to do it with. I have Blender, but I'd just rather find a way to avoid relying on myself creating objects that may or may not work out right.
So what am I asking?
I want to make something that resembles this:

[yes, the image is terrible quality, I know]
The actual rock part is my major focus, since I can work my way around the other objects. Any suggestions for what to use to make the land part? Any suggestions for the waterfalls and water (creating any body of water above ground is beyond me at this point)? Any input as to what bugs I should look out for? Preferably, the surface would have collision on all sides, but I'm willing to do whatever works.
I'm sorry to ask about what may be obvious, and very sorry if this is the wrong place for the thread. Hope you understand, and would appreciate any and all ideas and suggestions for this project. Thanks!
