To select the best vocabulary word to describe the artwork, it would depend on the characteristics of the artwork itself.
- If the artwork consists of defined, straight lines and angles, "geometric shape" or "geometric form" would be appropriate.
- If the artwork features flowing lines and natural curves, "organic shape" or "organic form" would be more fitting.
Without visual input, I can't determine the best descriptor. However, consider the characteristics of the artwork to choose accordingly:
- If it is based on structural patterns, "geometric."
- If it resembles natural forms, "organic."
Choose the option that aligns with the style of the artwork you are considering.
