Man, it's good to see you back again! I think you've got a good start going here, I like the low clouds, you have a good focal point, etc. It would be interesting to experiment with an ultra-low density cloud with sandy color to simulate windblown sand. Other than that perhaps mask your Fake Stones so they're less evenly distributed, especially in the background. One interesting thing is that people often have a hard time restricting surfaces from covering Fake Stones, but in this case it works well as it looks like sand has blown over and settled on the tops. Adding the blowing sand I mentioned above would really solidify that.
Looking forward to seeing more!
