I am a professional woodcarver and engineer who mainly works with digital 3D-modeling and sculpturing.
The sculptures are made of different kind of materials like wood, stone, bronze, concrete, etc.
The process of sculpting often begin with some sketches either on paper or in a digital 3D-model.

Then the sculptures are modeled in clay or carved in wood, stone or other materials.
Some sculptures are also a combination of the traditional way of making sculptures and modern cnc-milling.
