Using the circle select tool in Photoshop I created four layers for different values. I then applied the airbrush tool using the lightest color first with a large digital brush and then layering above it. Once I merged some layers I touched it up using the darken or lighten choices in the brush menus. Using a smaller brush size.

I inverted the select tool and did the same for the background.

After I flattened the whole file, I added a blur filter to soften the hard edges the select tool created.

This was done in Illustrator, but the old fashioned way of using the bezier curves and some gradient colors in linear mode.

This was for our Sayoc Tactical website that teaches CQC with edged weapons. It is still under construction though.

Sketch of the Fett. With coloring book style inks I rough out the placement with blue lines before I pencil an outline over that .
