I create textures and line drawing by hand with India ink and sharpie markers, mixing oil and water, salt, baking soda and vinegar, etc. Then I scan these elements into the computer and resize them .. put them in new compositions and color them.
Being in interesting environments is my number one inspiration. When I was kid I would take the subway all over San Francisco bay area, skateboard in old army bases and drain pipes, go to china town in San Francisco then end up in some suburb that had good handrails at an elementary school. Now, I am just wandering around Latin America, trying new food, looking at funny characters, etc.
