Drawing, like writing, tells a story that is colored through the interpretive lens of the observer. I've always loved how the art a person creates inspires, moves, becomes powerful to different people for a plethora of reasons. As I was looking through some paintings by Henri Rousseau, I found two that represented "civilization" and "barbarism." The paintings inspired me by their juxtaposition of two concepts: the instinct for survival versus the rituals for courting.
