Painting with cardboard

I decided to start looking at creating texture when painting with object throughout my sketchbook. After studying Richter's work, I wanted to look at created the rippled affect I can see throughout many of his painted over photographs. I really enjoyed painting with the cardboard. I feel that it gave me the opportunity to create structure within the paint which made it look a lot more interesting. In addition to that, I feel that the blend of colour worked well together. They created the dark to light tonal value that I desired. To conclude, I am happy with how this piece turned out, I feel that it has created an really interesting effect.
