I know it's scraggly and primitive, but I am having so much fun doing these. It helps me to get my brain going a little. I finally bought a coloring book called "Fantastic Cities", by Steve McDonald. All the coloring books are fun to look at. A long time ago I did lots of pen and ink drawing for a newspaper. I had a little weird artsy comic strip and got paid 5 dollars each week. This stuff reminds me of that, and I love just designing and playing with black and white.
My disclaimer is that I do know it is not done well-it's just for fun.
If you happen to print them off-I'd be so pleased if you took a picture of your work and posted it.
