I was never the most artistic kid growing up. I couldn't draw worth a damn, and whenever I sat down and tried to make something look like a human being in art class, I ended up just embarrassing myself.
So, I would go the Jackson Pollock route. Admittedly, it wasn't by choice.
So whenever I see someone who is capable of a true work of art, whether it be a drawing, painting, or an impressive piece of graffiti, I'm amazed.
