Here is a example from my current sketchbook. On this page I was experimenting with taking found images from skate magazines and creating a collage based skateboard graphic. When I create my sketchbook pages I try to make them as clean as I can and aim not to add large bodies of text which tend to distract the reader from the work.
Here is a page of drawings / collage experiments which I created. I first copied from some photos which I had taken and cut the backgrounds of them out. I then inserted some photos of the south bank in the background. These pieces are supposed to show stereotypes withing skating such as Graffiti and Young Teens.
