Hello. You did not present the image of the sculpture to which the question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
In a sculpture, relief is the term that refers to a sculpture that protrudes from a flat surface that is the base material of the sculpture's composition. There are two types of relief. The bas-relief is one that the sculpture projects little and was not made with the removal of a lot of material from the surface. This type of sculpture, is established very close to the surface of the base and is characterized by shallow cuts and more subtle and delicate modeling. The high relief, in turn, features a sculpture that protrudes far beyond the surface material. This type of relief presents itself with deep cuts, great removal of material from the surface and well-defined and prominent modeling.
