**Design Breakdown:**

1. **Color Palette:**
   - Change the color from mint green to a soft pastel blue for a fresh look.

2. **Shapes and Features:**
   - Replace the cactus shapes with simplified geometric forms, like pyramids and cones, to create a more abstract interpretation of plants.
   - Incorporate smooth, rounded edges instead of ribbed textures for a modern aesthetic.

3. **Arrangement:**
   - Maintain the staggered height arrangement but introduce a slight rotation to each piece for added visual interest.

4. **Background:**
   - Substitute the black pot with a light wooden planter to add warmth.
   - Replace the background greenery with a minimalist art print for a chic, contemporary feel.

5. **Additional Elements:**
   - Add a small decorative rock or pebble arrangement in front of the new plant shapes to enhance the scene's depth and texture.

This updated design retains a focus on modern decor while introducing fresh elements and a unique character.
