Similar to what Ralph said however you can do it Vi-hack style.
If I were you, start with a base colour, then add multiple ellipses of slightly higher brightness so it simulates small clumps of what looks like sand there, eventually it should come together nicely.
Then add the other pieces like the trophies and such on the ground.
Then make a separate Stickfigure for the background behind that.
you’re not gonna be able to hit the realistic levels of detail there, but you can manage it in a more simplistic style
look at jackfly’s backgrounds for example http://sticknodes.com/sticks/palm-tree-4-nodes/
