Here's a tee shirt I did for a summer camp in Westchester County. It's a cartoon version of their trail map-- still pretty accurate. I started by doing a light trace of their actual trail map to ensure that all of the lines would fall in the right spot. With the rest, I took some artistic liberties (for instance, there is not a bumblebee the same size as their building).
Fun to know that your work will be worn by a few hundred kids over the course of the summer.
