Like portrait sculpture, Figurative Sculpture creates it own unique challenges. Depending on the pose, an artist has to decide if an armature would be useful in the construction. Many times the clay will collapse upon itself it there is no underlying support. The next hurdle is understanding anatomy. To make a figurative sculpture an artist must understand proportion, skeletal structure, muscle structure and how the body structure changes with movement. Books on anatomy or live models are essential to the success of a representational figurative sculpture. It takes years of practice and a keen eye for detail to be an accomplished sculptor.
