I would say 93% another artist's idea and painting, 7% Rodney Pike's creation- it's a digital illustration.
I would say 100% Rodney Pike's creation, using another artist's idea as source material.
To attribute Pike's creation at this high a percentage to "another artist's idea" is like attributing 93% of a painter's painted canvas to Nature for creating all the raw materials that enabled the canvas cloth, oil paints, animal hair for bristles of the brush, technology to produce the lathe that spun the wood handle for the brush, and all the workers who contributed to the manufacturing of the painter's materials, AFTER nature provided the foundation.
