[SGP37] A small piece of nature

This is my contribution to Sunday's one hour prop challenge. No maya this time, I've used my own software to generate the landscape (Grand Designer) and Substance painter to enhance a bit the final result. 40 minutes on grand designer to find the right spot, tune the parameters and 20-30 minutes for the painting. I do not count the time spent in trying different things that have not made it to the final scene
