What little I have done was "hardshell technique".
I used aluminum window screen, stapled, crumpled, hot glued into place.
Over that, to create the hardshell on the cheap I used strips of heavy paper towels, dipped into a watery slurry of plaster of paris.
over the hardshell, I did my own, "ground goop". I used white carpenters glue, latex paint, water, sawdust that was screened through that window screen, keeping the finer stuff, a little plaster of paris again, and some disinfectant cleaner like pine sol. You want like a runny mud, so that you can sort of spread it with a paint brush. this fills the hardshell and lets you even out any real unnatural features in your shell.
If you make your ground goop dirt colored using latex paint or acrylics, then when you have it the way you want, you can add your grass while it is still wet.
For grass, I used the screened sawdust, stirred into it water based green wood stains. I created three different colors of grass using three different wood stains. If you want brown, just use the screened sawdust alone.
If you want flocking for trees, use some of the coarser sawdust and color with stains or acrylics.
for stone cliffs, I used the accoustic ceiling tile with broken edges. for stone wall, I ripped accoustic tile into strips, hacked it to create cracks and joints and stacked and hot glued it. Once painted, it becomes quite hard. Probably so does the spray foam and the styrofoam though.
None of this is my invention of course, I just took the advice out there and suited it to my budget and degree of laziness and cheapness.
This reply is a mess, but I learned everything I needed from these forums and some of the model railroader sites and groups.
many ways to accomplish this, it's a matter of picking the one you like best, both in terms of result sand the process itself.
