Taking your doodle to the next level

I have been doodling just not posting:( sorry. Most of my recent doodles have been using ball point pen on 3"x5" index cards. I really like some of the designs that I have been creating. I thought it would be fun to take these doodles to the next level, a painting!
I did this doodle on 11"x14" stretched canvas. I started by painting the entire canvas one color, orange (it's what I had on hand). Next, I painted some large shapes with black than some large white shapes, leaving the orange showing through in some areas. From there I just painted the way I doodle. Add a shape here, a line there, repeat to create patterns etc... Continue until a sense of balance is achieved.
