The essence of a rosebush branch:

Pencil Study of a Rosebush Branch

After having spent many hours squiggling away at drawings attempting to capture the patterns created by the sunlight coming through the window or streaming through the trees, this simple line / shape drawing was like a breath of fresh air after being cooped up for too long.  The reason I do the squiggles is so that I look carefully enough at my subject to understand its basic structure.  My ultimate goal is always to reveal the unique pattern structure and capability of movement in the most simple manner.
