Six Flags: Heroes and Villains

It’s a comic book kid’s dream! Our lead designer and illustrator, Nathan Owens, was asked to create illustrations of iconic DC Comics characters in his signature Trophy Head, metallic linework style for merchandise in Six Flags theme parks. While Six Flags provided the reference material, Gold Sheep added their creative spin on some of their most beloved characters, from Wonder Woman to The Joker, who made their appearance on shirts in the Six Flags theme parks nationwide.

The Process Case Study: The Joker

The Reference Photo Selection

It all starts with selecting the right reference. We received a set of reference photos to choose from and Nathan set out to imagine how each would look in his metallic linework style. He also took into consideration iconic imagery- like The Joker’s signature smile.

The Line Work

It all starts with choosing the defining lines for each particular piece. In the case of The Joker, that would be his wicked smile that defines the cheekbones, the lips, the outline of the nose, eyes and ears. Those are drawn using a custom line brush in Illustrator.

From there, internal lines are added at about 1/2 to 1/3 width to fill the remaining areas. The blend tool was used to create transition lines, but sometimes those need to be altered, depending on the area. All together- it’s a whole lot of MF lines.

Color & Gradients

The last step is to fill in the color. We want to stay true to the reference material, so we eyedrop those colors, figure out the highlights, shadows, and midtones, and define the gradient. Then the gradient is applied to every line. Yes- every single line. Angles are adjusted as needed for the metallic treatment, giving the faces and logos that 3D effect.
