Drawings on the train, standing, happen to be a little shaky at times, especially during rush hour. And this is also when there is a feeling of a rush, an urgency. The page here is just the beginning of something.
Do you want to complete the drawings? Go ahead. Drag the image to your harddrive, print it out. Use any tool, anything. Then email me the result or just upload it as a comment. Let's see what we can come up with... : )
