Moving further along now (about 12 hrs of effort thus far) you can begin to see the transformation from the planar to the third dimension.
The difficulty now is keeping aware of "cross-cut" fractures which can occur when removing deep portions of stone. This particular stone is white limestone (likely from Indiana, USA) and is quite prone to easily fracture without changing the "ring" of the stone. This is quite deceptive and must be dealt with by keeping precise and sharp chisel blows without allowing too much surface area stress.
My eventual goal for the "feet" is to detail in a set of humanistic features fashioned to appear more as hands. The next step in progression is to bring about overall depth contrast by lowering the would-be chest cavity and allowing the knees, feet and middle of the face to stand out. This will then give me the perspective for bringing the inner portions of the wings way inward - giving a stretched 3D space.
