Full range of values and playing with warm against cool colors:

Watercolor study of Cactus Plant

The watercolor sketch and I had a difference of opinion during our session together.  The painting wanted more detail and I wanted to be loose and expressive.  Clearly, neither one of us got our way and the painting remains unsettled.

My goal was to use a full range of values to create the sense of sunlight on the cactus.  I also wanted to make use of playing warm against cool colors for enhanced contrast.
