I just stumbled on an interesting collection of drawings at: http://www.drawninblack.com/ The site is basically a pile of black and white (mostly) drawings that the guy found interesting. Most of which demonstrate more polished skills than I have… but it was fun to paw through them. Along the same vein, here is a pencil drawing I did after a trip I took to New York City.
