These are the elements that make for good interior decorating in my opinion:

  • Dark brown wood
  • Dark brown leather
  • Books
  • Plants
  • Flowers
  • Candles
  • Lighting
  • Icons and other art
  • Not much else

Simplified: wood, leather, paper, life, light, art, and not much else

Even simpler: plants alive and dead, cows dead, light, and pictures
