I am thrilled, tickled pink :-) with the progress of this piece. I call this zigzag style because as you can see, the rendering of lights and shadows is accomplished with the repetition and stacking of zigzag shapes. One great advantage to this style is that transparencies are not required.
The inspiration for this style came from studying Rockwell Kent's illustrations. I truly believe that if we reach back, embrace our heritage as image makers, then leap forward with the new tools available to us, that we will make new styles of art. This is what is so exciting about the new renaissance of illustration.
