So a while ago, someone sent me some pictures of a sidewalk artist Julian Beever's work. I don't know if you've seen it or not but it's definitly worth Googling him.
Ever since then I've wanted to try this technique myself. So tonight, despite all the other things I probably should have been doing, I tried a small scale drawing. Something simple, something quick.
I think it came out well enough to give it another try...maybe even something over the top.
