He has a signature style often consisting of a great sense of motion through variation of line, perspective, ink splatters, a smart use of white space, limited but high impact color, and distortion.
While his style is not to everyone's taste, I am fascinated by it. His art is not pretty but I am intrigued by every composition. I am drawn to the "creepiness" and the unsettling feeling that seeps from every picture. I imagine he paints and draws furiously, using emotion (and other chemicals) as much as skill to create.
I love this study of a bullfight. The shapes are simple but the action is intense,highlighted by a purposeful use of color.
Even this illustration of "Sadie," a dog I assume he loved, has a quickness in it's lineand a sense of emotion.
Owning an original piece of his art is a future goal of mine but until then I will settle for the six-pack version of his illustrations from the Flying Dog Brewery (from Aspen, Colorado, no less).
I wish I could post all of my favorites of his work, but these few will have to suffice. Google him for more awesomeness!
