I now have a lot of pictures how I did it of course the first thing many people do is play with wood to create a specific structure as you wish. I uses rolls of leg plaster to get a certain shape than Bragdon Enterprices Latex Rubber Rock Molds the best there is. I also use hammer and chisel to get more refinement the colors that is always what you like I used water colors and find sand colors very beautiful the rocks that you see are just three colors that are applied very water-wise. I look closely at real pictures and been 2 years ago in the USA made hundreds of photos of rocks,  you have everything over there.
