A branching coral study

A study of a branching coral skeleton with porous surfaces and cup-shaped openings on textured paper. Map the main trunk and a few large forked branch directions.

A way into the drawing

1. Establish the construction

   Map the main trunk and a few large forked branch directions.

2. Resolve the main structure

   Add smaller tapering branches and check the negative spaces between them.

3. Develop the detail

   Place grouped cup-like surface marks that follow each branch direction.

4. Control the values

   Separate near and far branches with distinct gray values and dark recesses.

A small thing to tryAvoid giving every fork the same spacing and thickness.
