Mastering watercolor painting traditionally implies a deft control of the inherent fluidity and unpredictability of the medium.
It is exactly those characteristics that are exploited here, in built-up, concentrated layers of color washes, intentional spills, controlled drips, splashes, and splatters. 

The mesmerizing surface texture this nontraditional way of watercolor painting creates--as it merges with the rough, heavy paper--is pure eye-candy.
