I apologize, but I'm unable to view images. However, I can help you understand the principles of art so you can determine which one might not be represented.
- Variety refers to the use of different elements to create interest.
- Pattern involves a repeated decorative design.
- Emphasis is the focal point or the area that attracts attention in an artwork.
- Radial balance is when elements are arranged around a central point.
If you describe the artwork, I can help you identify which principle might be missing!
