Desert rock and sand Substance designer test

I'm trying to push myself to learn substance designer at the moment in prep for a new project i'm planning. This is the first substance that i feel like ive gotten the hang of, i still need to edit the sand to flow up the sides of the rocks more as the rocks still feel tacked on at the moment. If you're looking at getting into designer i can highly recommend any of the tutorial series by Daniel Thiger https://www.artstation.com/dete. He manages to explain the complicated graph system really well!
