A fragment of cork bark

A study of a curved cork-bark fragment with deep fissures and a smoother concave inner face on textured paper. Block in the curved slab and the thickness of its broken edges.

A way into the drawing

1. Establish the construction

   Block in the curved slab and the thickness of its broken edges.

2. Resolve the main structure

   Divide the outer face into large connected fissure groups.

3. Develop the detail

   Add smaller cracks and show the smoother inner curve at one end.

4. Control the values

   Deepen the fissures while keeping the cut edges lighter than the outer bark.

A small thing to tryOrganize the largest cracks before adding small surface marks.
