Terrain in the making

I've been looking at various blogs about making terrain cheaply. A lot use Aquarium pieces but here in NZ they are a bit more pricey. However I did find these in the $2 shop the other day - they were $3 (ha ha) so I got 2

Each bunch has 7 different sprues and each sprue is made up of 4 different elements which I think will go well in making different CD based Jungle/Forrest terrain.

 I will add to this a couple of grass tufts that I picked up a few years ago and I think it will look quite good.
