The art of sculpture is a hand made are where you have ur hands on the meterial as u are working with it, while a printmaking is more like a techonology making the type of art where you wouldn't touch or feel the material u are working with but instead rotating and flipping it as you work with it through a computer system. The sculpture peice of art has more value to the person that once made it because its men made not a computer system made type of art.
Wouldn't it be rhythm, the use of recurring elements to direct the movement of the viewer's eye's through the product of art and give a sense of unity to the composition. correct me if im wrong
