Cactus fine ink study

One small barrel cactus in a plain round pot, broad vertical ribs and grouped sparse spines. Practice structure, perspective and developed values in fine ink.

A way into the drawing

1. Establish the main shapes

   Place a rounded cactus above a pot ellipse.

2. Connect the structure

   Connect the pot sides and curve the ribs around the cactus.

3. Develop the drawing

   Resolve the connected planes and overlaps, then build layered details and a full range of local values. Preserve clear paper highlights.

A small thing to tryKeep the spines sparse enough to preserve the broad form.
