What Success Looks Like

  • Large dune geometry with smooth, wind-sculpted curves
  • Sharp shadow line dividing lit and shaded faces of the dune
  • Correct sand material — orange/golden colour, subtle granular texture at close range
  • Strong sense of scale (dune should feel massive)
  • High contrast between bright sunlit sand and deep shadow, with correct exposure handling
