I've been experimenting With materials & have made some saga terrain out of some off cuts of 10mm soffit board & some rocks
Above is a piece of rocky terrain & below some scrubland
I used a battery grinder with a flap disc in to 'sculpt' the peices.
I also added some old bushes/trees & some grass tufts just add a bit more depth. I'm quite pleased with them & think I will try a pond & a river next.
