Park Party and Subway Sketches

As the Summer comes to a close, Im spending as much time as I can at the park trying to coax tourists into my chair, before the autumn chill and subsequent winds set in making it impossible to draw. I've missed the majority of Summer drawing in the park due to my back injury, but thank God Ive gotten a LOT better and no longer require the use of the cain, or even the chair that I habitually carried. These are a series of sketches done at the park(which customers rejected!!) on the subway, and at a party. Can you guess which is which? Enjoy.
